7.9.2 Status Output Functionality
SC10-2: Up to four convertible inputs may be used as a Status Output.
XS/SC26-2: Up to 32 convertible inputs or Safety Outputs may be used as a Status Output. Solid-State Safety Outputs may be split and used as Status Outputs. Relay Safety Outputs cannot be used as Status Outputs and cannot be split.
Status Outputs can be configured to perform the following functions:
Bypass
Indicates when the Input to the Bypass Function Block is bypassed.
Mute
Indicates a muting active status for the Input to the particular Muting Function Block:
• On when a mutable input is muted
• Off when a mutable input is not muted
• Flashing when the conditions to start a mute-dependent override exist (an inactive muting cycle, the mutable Safety Input is in the stop state, and at least one muting sensor is in the stop (blocked) state); not available for Virtual Status Output
• On during an active mute-dependent override function (not a bypass function) of a mutable Safety Input Output Delay In Progress
Indicates if either On- or Off-Delay is active.
Track Input
Indicates the state of a particular Safety Input.
Track Input Fault
Indicates when a particular Safety Input has a fault.
Track Any Input Fault
Indicates when any Safety Input has a fault.
Track Input Group
Indicates the state of a group of Safety Inputs, for example, which Safety Input turned off first. Once this function has been indicated, the function may be re-enabled by a configured Reset Input. Up to three Input Groups can be tracked.
Track Output
Indicates the physical state of a particular Safety Output (On or Off).
Track Output Fault
Indicates when a particular Safety Output has a fault.
Track Output Fault All
Indicates a fault from any Safety Output.
Track Output Logical State
Indicates the logical state of a particular Safety Output. For example, the logical state is Off but the Safety Output is in an Off-Delay and not physically off yet.
Track Function Block State (XS/SC26-2 FID 2 or later and SC10-2) Indicates the state of a particular Function Block.
Track Press Function Block (XS/SC26-2 FID 4 or later)
Indicates the state of a number of Press Function events; see XS/SC26-2: Press Control Status Output Functionality on p. 71 for details.
Waiting for Manual Reset
Indicates a particular configured reset is needed.
Note: If the manual reset input is connected to a Reset OR block, this status output cannot be used.
System Lockout
Indicates a Non-Operating Lockout Condition, for example unmapped input connected to 24 V.
7.9.3 XS/SC26-2: Press Control Status Output Functionality
The Press Control Function block has multiple inputs and outputs. This results in a status output function that is not a simple on/off for an individual item. The Press Control block's status output has seven different events that can be signaled via the status output. The Press Control block's status output can be configured to provide one, two, or three signals. Each signal from the Press Control block's status output can be as follows:
• Solid On
• 2 pulses per second
Figure 47. 2 Pulses Per Second
t2
2 pulses per second t3 t1
t1 = 100 ms, t2 = 100 ms, and t3 = 1 second
• 3 pulses per second
Figure 48. 3 Pulses Per Second
3 pulses per second t2
t3 t1
t1 = 100 ms, t2 = 100 ms, and t3 = 1 second
The Press Control block status output is only available as physical status outputs. Each physical status output can be used to signify three different events.
The following figure shows the default settings of the Press Control Function block’s status output:
Figure 49. Track Press Function Block Properties
The default setting of the function block configures three of the IO pins as status outputs. If all seven events are not required to be displayed for a given application, use the slide bar on the right of the figure to select fewer pins. Moving the bar up one position reduces the number of terminals to two, moving the bar up two positions reduces the number of terminals to one.
The functionality of each event is as follows:
• Waiting for Reset—Turns on when a reset input is needed, after the non-mutable and mutable (if configured) safety stop inputs return to the ON state
• Ready to Run/Run—Is on any time the press is ready to run (mutable and non-mutable safety stop inputs are on and reset) or the press is running in the up or down stroke
• SQS Stop—Turns on when the press ram reaches the Sequence Stop point
• PIP back check alert—Turns on when the press is ready to run and an attempt is made to start a press cycle and the PIP (Part in Place) input, if configured, is off or has not turned off then back on (part not removed and replaced)
• Safety Stop—Turns on when either the mutable or non-mutable safety stop input turns off, the GO input node goes low (when configured for Manual Upstroke Setting) before SQS, BOS, or TOS is reached (depending on settings and portion of the process)
• Operational Fault—Turns on when mutually exclusive operational inputs are on (for example, TOS and BOS, TOS and SQS, TOS and PCMS, SQS and BOS, etc; if more than 3 seconds elapse between the SQS and PCMS signals both turn on, if configured)
• System Fault—Turns on when a system fault exists
