33.1  Safety Operation Mode

33.1

Safety Operation Mode

There are two safety operation modes: TEST MODE and SAFETY MODE. Running normally as a safety system or changing 
a safety program and safety parameter can be selected.

*1 The same restrictions apply to this mode as those for SAFETY MODE.

Checking the safety operation mode

The safety operation mode can be checked in three ways.
 • TEST LED of the safety function module (

 MELSEC iQ-R CPU Module User's Manual (Startup)

 • "Safety Operation Mode Switch" window of the engineering tool (

 GX Works3 Operating Manual)

 • Module information list of the engineering tool (

 GX Works3 Operating Manual)

 • Safety special register of the Safety CPU (SA\SD205) (

 Page 885 List of Safety Special Register Areas)

Function different 
(modified or 
restricted) from the 
standard CPU

PID control function

The PID control instructions cannot be used in safety 
programs.

Multiple CPU 
system function

Data 
communications 
between CPU 
modules

The Safety CPU supports only data communications using 
the CPU buffer memory. Data communications using the fixed 
scan communication area is not supported. The data 
communications using the fixed scan communication area is 
available between the CPU modules other than the Safety 
CPU.

Multiple CPU 
synchronous 
interrupt

Multiple CPU synchronous interrupt (I45) is not supported 
since the execution of safety programs is prioritized.

Latch function

Safety devices, safety labels, and standard/safety shared 
labels cannot be latched.

Device/label initial value setting

An initial value cannot be set for safety global devices, safety 
local devices, safety global labels, safety local labels, and 
standard/safety shared labels. To set an initial value to those 
devices and labels, create a program so that the safety state 
can be secured and the value is set only at the start-up.

Device/label access service processing 
setting

Even though this function is set, the scan time of some 
functions (operations) becomes longer than the specified 
time. The following are added to those functions.

• Safety local devices (label) batch/registration monitor
• Current value change of the safety labels/safety devices
• Switching safety operation mode
• Safety data identify check

SLMP communication function

Safety devices cannot be accessed. Also, the command 
execution status differs.

Safety operation mode

Description

SAFETY MODE

This is a mode for operating the safety system controlled by the Safety CPU.
In this mode, Safety CPU safety programs and safety parameters cannot be changed. Only device data values in safety 
programs can be changed.

TEST MODE

This is a mode for performing maintenance (such as setting changes and tests) of the safety system controlled by the 
Safety CPU.
In this mode, Safety CPU safety programs and safety parameters can be changed. Device data can be changed by 
performing a device test.

SAFETY MODE (wait-for-restart)

*1

The system switches to this mode during the period from immediately after safety operation mode is changed to 
SAFETY MODE when in TEST MODE until the CPU module is turned off or is reset. Even if safety operation mode is 
switched to SAFETY MODE, safety operation mode becomes this mode until the CPU module is powered on or is 
reset. Programs are not executed in this mode. An error occurs if the CPU module is the RUN state.
