Replacing a Safety I/O-module
When you replace a Safety I/O-module, its configuration is retained and transferred to the new
module when you restart the system. The programming environment will tell you is the new
module is incompatible. You must carry out appropriate tests to verify whether there are any
other failure modes such as using the wrong terminals or making wiring mistakes.
The text below describes how to replace a Safety I/O-module with a Safety I/O-module of the
same type.
CAUTION
Unsafe and undefined machine state
Risk of injury
Turn off the power supply of the control unit and the c250-S modules before
replacing a Safety I/O-module.
After you have replaced any Safety I/O-modules, separately test the safety
function before you restart the machine or system.
Design you wiring tests such that you will reliably discover the use of a
wrong terminal.
NOTE
You must set up your entire project again if you replace a Safety I/O-module
with a module of another type. If so, refer to the Operating Instructions of the
new module.
Procedure
•
Verify that the new module meets the following requirements:
o
Same type of device
o
Same or higher version, see section
►
5.1 Labelling and Identification
•
Enable the safe system or machine state.
•
Turn off the power supply of the control unit and the c250-S modules.
•
To remove the old module (see sections
►
6.1.4 To Disconnect Two Modules and 6.1.5 To
Take Down a Single Module):
o
Dissolve the line of c250-S modules by pressing the unlock button of the
module to be separated from the module to its left and sliding both modules
about 1 cm apart.
o
Push the module up and against the metal spring located on the underside of
the rail guide.
o
Tip the module away from the rail as shown in the illustration.
o
Pull the module down and out of the mounting rail.
•
Locate the FSoE address at the address coding switch of the module you are replacing and
transfer that address to the new module
