7-1. Checking the CPU When an Error
Occurs
x Ifacommunication error or anerror inthe FP3 transmitter masterunitoccurs, checktheLEDstatusfor theFP3 transmitter
master unit and the FP I/O transmitter unit.
See pages 91 to 98 and 103 to 107 for details about the operation monitor LED status when an error occurs.
x When a communication error occurs , the CPU of the FP3/FP10S detects the error using a self-diagnos ti c function.
J
Checking method
1) The operation monitor LEDs of the CPU show the following LED status.
RUN
PROG.
TEST
BREAK
ERROR
BATT.
ALARM
RUN LED: ON
ERROR LED: ON
Other LEDs: OFF
2) With the FP3 CPU, special internal relay R9002 turns ON.
3) Self-diagnostic error code “E40” can be read by the NPST-GR software and FP programmer II.
Error code “E40” is stored in special data register DT9000 for the FP3, and in special data register DT90000 for
the FP10S.
See the “FP 3/F P 10S HARDWARE Technical Manual” for details about the special data registers and self-diagnost ic
error codes.
4) The slot No. of the FP3 transmitter master unit that is generating an error can be checked with special data registers
DT9002 and DT9003.
Example:
x When an error is generated in the FP3 transmitter master unit mounted in slot No. 3 of the master backplane.
Special data registers: DT9003, DT9002
