- 1 7.1 Procedures before System Operation
(1) Install the modules
Install the safety power supply module and the safety master module on the
safety main base unit and wire the system. After pre-operation check, conduct a
a hardware test on the safety master module. (Refer to Section 7.2.)
(2) Connect the cables
Connect remote modules to the safety master module via CC-Link dedicated
cables, and then make settings of the remote modules. (Refer to Section 7.6.)
(3) Write parameters to PLC
Perform write to PLC using GX Developer to write network parameters to the
( Refer to Section 6.1.)
safety CPU module. (Refer to Section 6.1.)
(4) Line test
In a line test, check status of a data link between the safety master module and
all the remote modules. If any problem is found in the line test, modify network
parameters and safety parameters according to the results of the test. After
that, check settings of the remote modules and connection status of the CC-
( Refer to Section 7.8.)
Link dedicated cables. (Refer to Section 7.8.)
(5) Write user program
Perform the write to PLC function of GX Developer to write a user program to
the safety CPU module.
(6) Check operation of the user program
After writing the user program, switch power of the PLC from OFF to ON or
cancel the reset state of the CPU module, and then execute the user program.
Check the CC-Link Safety operation status, I/O signal status, etc. using GX
Developer's monitor function, etc. Make sure the program runs properly.
(7) Change to SAFETY MODE
Change the safety CPU operation mode to SAFETY MODE using GX
Developer. For how to change to SAFETY MODE, refer to the QSCPU
User's Manual (Function Explanation, Program Fundamentals).
