Remote STS Codes from a PLCĆ2 or 1774ĆPLC Processor
STS codes that may be sent from your PLC-2 (or 1774-PLC)
processor to your computer include:
STS Code Explanation ➀
10 The command message (command code, subĆcommand code, size of the
command or requested reply size) was incorrect.
20 There are verification errors within the host PLC processor.
30 A condition exists at the PLCĆ2 processor that requires manual intervention,
such as:
• the cable between the module and the processor is unplugged
• the processor is faulted
40 A communication error on the cable or on backplane access between the
module, and the processor has aborted message execution.
50 An attempt to access an illegal address in the PLCĆ2 processor has aborted
message execution. Illegal access may result from access outside:
• the data table as defined by the PLCĆ2
• a memory access window (protected commands only)
Illegal access may also mean that the PLCĆ2 processor has attempted to
communicate with a PLCĆ3, PLCĆ5, or an SLC 500 processors that does not
have the proper compatibility file.
60 Execution of a command at the PLCĆ2 processor is disabled by a switch
option.
70 The PLCĆ2 processor is in Program or Remote Program mode, or the 1771ĆKA
is in Download mode. Alternatively, this code can also mean that the PLCĆ2
processor is not in Program or Remote Program mode.
80 Execution of protected commands at the PLCĆ2 processor is inhibited because
its PROG light is on.
➀ The error sets the remote error bit for the associated rung.
