CHAPTER2 CC-Link Unit

2-7-6 Service mode (SVCE)

This input is valid when the service mode function of the controller main body is valid.

The service mode input is used to inform the controller whether the current status is the

service mode status or not. In the service mode status, keep this input OFF (the contact is

open.).

MEMO

When the status of the service mode input varies during robot operation, the opera-

tion execution will be interrupted.

MEMO

When the service mode function is valid, DI15* on the parallel I/O also functions as

the service mode input. Accordingly, it will be switched to the service mode status if

either of two service mode inputs is merely turned OFF. To escape from the service

mode status, it is necessary to turn ON both service mode inputs.

* DI7 when the SRCP/SRCD series controllers are used.

2-7-7 Initial data processing end flag

This is an input for performing the handshake to start communication between the con-

troller and the master station sequencer (PLC).

During controller start-up, or when an error occurs on the CC-Link system and commu-

nication with the master station was not performed, the controller sets the initial data

request flag to ON. When the initial data request flag turns ON, set this input to ON from

the sequencer (PLC). Doing this makes the controller set the initial data request flag to

OFF, so you should then turn this input OFF from the sequencer (PLC).

Refer to “2-6-1 Starting data exchange with the controller” for more detailed informa-

tion.
