Emergency stop devices complying with IEC/EN 60 204-1 must be effective in all operating modes of the automation equipment. This manual contains all information regarding the safe and correct operation of the I/O modules of the TURCK piconet® product range. It is imperative to observe the applicable safety and accident prevention rules of the specific application.
The coupling module detects the I/O data of the connected expansion modules via a high-speed (2 Mbps) interference-tolerant IP-Link network. A detailed description of the IP-Link optical system is available in Chapter 2 of this manual. The length of the optical cable between two modules and thus the distance from module to module must not exceed 15 m.
2 IP-Link
If a link module is to be used without expansion modules, the IP-Link connections must be bridged. The IP-Link cycle time of these modules can be increased because the polling response time depends on the internal cycle of the expansion module. When installing the IP-Link cable, the minimum bending radius must be 50 mm (static) and 55 mm (dynamic).
The IP-Link connector is a male fiber optic field cable connector and provides an IP67 rated plug-in connection in combination with the female connector of the corresponding splice or extension module.

3 Register communication
Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
The first two bytes of user data are not used for process data exchange, but are written or read from the register set of the piconet® module. For adjustments to the piconet® module via register communication, the write protection of the register must first be reset. The command to write to the register and thus enable communication with the register via password input is given by the control byte of the module.
The data bytes of the output data card of the modules contain the values to be transferred to the respective registers. In which section of the output data map of the module data bytes 0 and 1 are contained depends on the type of fieldbus system used and therefore on the data mapping of the modules. On request, the module type is indicated by the input data bytes, depending on the module and data mapping.
4 General technical information
If the load voltage is switched off (eg in an emergency stop), the function and supply of the bus and the input function will be maintained. With digital output modules with total current IΣ = 12 A, the supply voltage is provided by the M8 male connector. With the digital input/output modules, the ground potentials (GND) of the supply voltage and the load are connected.
With the analog input/output modules, these ground potentials are separated, to ensure galvanic isolation of the analog signals from the operating voltage. If you use UL for a feed-through arrangement, please note when connecting a module without galvanic isolation between UB and UL (i.e. all digital modules) that galvanic isolation is neutralized by a feed-through of UL. Please note during connection that with a nominal voltage of 24 VDC, the functionality of the modules cannot be ensured from a voltage drop of 6 V on.
5 Diagnostic LEDs for local errors
Local errors of a link module (SxxL-0404D-xxxx) Local errors are errors of the piconet® module or the IP link. A Counting starts with n = 1 with the last connected expansion module against the direction of the fiber optic cabling backwards in the direction of the connector module. IP link errors can usually be attributed to the inappropriate use of the fiber optic cables.
6 IP-Link coupling modules
The switching modules transfer I/O data from the digital and analog sensors or actuators connected to the module to the fieldbus. They also collect I/O data for the expansion modules via the interference-immune fiber optic link (IP-Link). This data is bus-specifically processed by the switching modules and transferred to the respective fieldbus.
In addition, it is possible to connect 4 binary switches or sensors as well as 4 binary actuators directly to the coupling module. From the fieldbus point of view, the coupling module with all connected expansion modules is a single node with a correspondingly large number of I/O signals. It can thus be considered as an IP67 remote I/O network with a single fieldbus interface.
The connection module automatically detects the connected expansion modules during the start-up phase and automatically maps the I/O data to the fieldbus process image. These digital I/O modules combine 4 digital inputs with a 3 ms input filter and 4 digital outputs in a single device. With M8 connection technology modules it is the top four connections (C0 to C3), and with the M12 technology modules the two top connections (C0, C1) with two inputs on one connector.
Please read the description of the diagnostic LEDs in case of local errors of the coupling and extension modules in chapter 5 of this manual: Fieldbus-specific diagnostic indications via LEDs are described in the "Troubleshooting and diagnosis" chapter of the manuals the aforementioned. . Detailed information on field bus-dependent module diagnostics can be found in the "Troubleshooting and Diagnostics" chapter of the aforementioned manuals.
7 Digital input modules
The devices are available as stand-alone or expansion modules and differ in connection technology and input filter speed. Digital input modules of type Sxxx-0800D-x00x detect binary control signals at the process level and transmit them to a higher-level automation device.
8 Digital output modules
The digital output modules transmit the binary control signals from the automation device to the process level actuators. This makes these modules particularly suitable for applications where not all outputs are active at the same time or where not all actuators require signal currents of 2 A. Detailed information on the fieldbus-dependent diagnostics of the modules can be found in the chapter "Error handling and diagnostics -tics" of the manuals mentioned above.
4 A The digital output module IE2808 connects the binary control signals from the automation unit to the actuators at the process level. This makes these modules particularly suitable for applications where not all outputs are active at the same time or where not all actuators draw 0.5 A of current. The control byte is only visible if the module is operating in complex mode.
The status byte is only visible if the module is operated in the complex mode. The behavior of the outputs in the event of a communication error can be defined via the Enable default status register R32 and the default status register R33. To write to the register, it is first necessary to reset the write protection in the code word register.
Register R33 defines the status of the output in case of an error (when Watchdog is activated). In the event of a communication error, all outputs are now set to OFF, except output 3. Output errors are only displayed (both on the LED and in the status byte) as long as the error occurs on the outputs.
9 Digital combined modules
The Sxxx-0800D-xxxx type device is designed to connect 4 binary switches or sensors and 4 binary actuators. The devices are available as stand-alone or expansion modules and differ in connection technology, input filter speed and different permitted output current values. These digital I/O modules combine 4 digital inputs with an input filter of 3.0 ms or 0.2 ms and 4 digital 24 V DC outputs in one device.
The outputs are suitable for load currents of 0.5 A; they are short-circuit proof and protected against reverse polarity. The device type Sxxx-0800D is designed for the connection of 8 binary switches or sensors and 8 binary actuators. These digital I/O modules provide 8 digital inputs with a 3.0 ms input filter or alternatively 8 digital 24 V DC outputs.

The process data is entered in the default settings in two's complement format (-1 corresponds to 0xFFFF). Please refer to the mapping descriptions in the chapter "Data mapping of the piconet® modules" of the respective bus-specific manuals.
The filter register assignment of the Sxxx-40A-x007 module is the same as that of the Sxxx-40A-x004 module. In the temperature range of the Pt100 sensor in 4-wire technology, the module setting has a resolution of 0.1 °C. wire break, is displayed via error LEDs. The module is parameterized via fieldbus or the additional configuration tool "I/O-ASSISTANT" via the configuration interface. additional current consumption of the module).
The settings of one channel always affect all other channels of the module and are therefore valid for the entire module. If you use UL for a feed-through arrangement, please note that galvanic isolation is neutralized by the feed-through of the load voltage when a module without galvanic isolation is connected between UB and UL (i.e. all digital modules). Selection of the 2-, 3-, or 4-wire measurement mode is read from the attribute register of the first channel.
If the "Show Siemens extra bit" parameter (R32, Bit 4) is activated, bits 0..2 of the process data are used for status evaluation. The default setting of the module is: a resolution of 0.1 °C in the temperature range of type K sensors. wire break, is indicated via error LEDs. Measurement error < ± 0.5% of final measurement value Power consumption. additional power consumption of the module).
The longer the cable, the greater the measured error, depending on cable length, power loss, and interference. Since the coefficient is determined at a reference temperature of 0 °C, the influence of the reference temperature must be. Loss of the cold junction in the connector: If the cold junction is outside the range of -50 to +100 °C, an error is indicated.
