Appendix B System Signal Variables
High-Speed Counter Variables For GuardPLC 1200 and 2000
Controllers
The GuardPLC 1200 and GuardPLC 2000 controllers support these
variables for counter I/O parameters.
AO[0x].Value
(1)
Write Output value of analog output channels
Voltage mode: -10V…10V = -1000…1000
Current mode: 0 mA…20 mA = 0…1000
for values between -1000… 0, the output current is 0 mA
Board.SRS Read System.Rack.Slot
Board.Type Read Module type
0xFB04 analog output module for GuardPLC 2000 controller
0xFFFF missing module in GuardPLC 2000 chassis
Board.State Read Error mask for the module
0x000 I/O processing may be running with errors
0x001 No I/O processing (CPU not in RUN)
0x002 No I/O processing during start-up tests
0x004 Manufacturing interface running
0x010 No I/O processing due to faulty parameterization
0x020 No I/O processing due to exceeded fault rate
0x040 No I/O processing because configured module is not plugged in
(1) 0x = output channels 01…08.
