Remote STS Codes from a PLC2 or 1774PLC 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, subcommand 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 PLC2 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 PLC2 processor has aborted

message execution. Illegal access may result from access outside:

•the data table as defined by the PLC2

•a memory access window (protected commands only)

Illegal access may also mean that the PLC2 processor has attempted to

communicate with a PLC3, PLC5, or an SLC 500 processors that does not

have the proper compatibility file.

60 Execution of a command at the PLC2 processor is disabled by a switch

option.

70 The PLC2 processor is in Program or Remote Program mode, or the 1771KA

is in Download mode. Alternatively, this code can also mean that the PLC2

processor is not in Program or Remote Program mode.

80 Execution of protected commands at the PLC2 processor is inhibited because

its PROG light is on.

➀

The error sets the remote error bit for the associated rung.
