Description Solution
16#1500 Remote module communication timeout
Make sure the module is properly connected to the CPU
module and turn the modules on again.
16#1502 Incorrect parameters
Check the parameter in HWCONFIG. Download the
parameter again.
16#1503 Extension module communication timeout
Make sure the module is properly connected to the CPU
module and turn the modules on again.
16#1505
The actual placement of the extension
module is not consistent with the
configurations.
Check if the setting in HWCONFIG is consistent with the
actual placement.
12.3.7.3 ERROR LED Indicators Blinking Every 0.2 Seconds
This happens when the 24 VDC power supply for the remote module is not sufficient. Check the power supply. If the
power supply is normal, remove the extension module from the CPU module and then check if the SCM remote module
is out of order. Error codes:
