These bits update once every 100
mS to indicate that the
communication card is still updated
by the central TPU processor.
Communication Event Log (8 Registers Defined)
Whenever a communication error occurs, the TPU2000/TPU2000R generates an exception response to the
rejected command. Registers 40172 through 40179 contains information on the last communication error
experienced via the front communication port, rear INCOM port or the RS232/485 ports resident on the relay’s
communication card. Table 5-18 lists the register definition for the event log.
