Safety Attributes

The Safety Controller object provides safety status and safety signature
information. The SafetyTask and SafetyFaultRecord attributes can capture
information about non-recoverable faults.
See the GuardLogix Controllers User Manual, publication 1756-UM020.

SerialPort Attributes

The SerialPort object provides an interface to the serial communication port.
Instruction Description
GSV Specifies the baud rate. Valid values are 110, 300, 600, 1200, 2400, 4800, 9600, and
19200 (default).
GSV Specifies the specific driver.
Value Meaning
0xA2 DF1 (default)
0xA3 ASCII
GSV Specifies the number of bits of data per character.
Value Meaning
7 7 data bits (ASCII only)
8 8 data bits (default)
GSV Specifies the amount of time to wait for the data carrier detect (DCD) to become low before
erroring the packet. The delay is in counts of 1 s packets. Default is 0 counter.
GSV Specifies the parity.
Value Meaning
0 No parity (no default)
1 Odd parity (ASCII only)
2 Even parity
GSV Amount of time to delay turning off the RTS line after the last character has been transmitted.
Valid value 0...32,767. Delay in counts of 20 msec periods. The default is 0 msec.
