Module
Peculiarities when reparameterizingBehavior of the
inputs/outputs
S7-300, ET 200, I/O modules with intrinsically-safe signals
6ES7 321-7RD00-0AB0
SM 321; DI 4 NAMUR
Supply the last valid
process value before
parameterization
SF LED shines:
If there was a pending diagnosis before
reparameterization, the SF LEDs (on the
CPU, IM, or module) may still be shining
although there is no longer a pending
diagnosis and the module is working
correctly.
Remedy:
• Only reparameterize when there is no
pending diagnosis on the module, or
• Remove the module, and then plug it in
again
6ES7 322 5RD00-0AB0
SM 322; DO 4 15V/20mA
Output the last valid
output value before
parameterization
6ES7 322-5SD00-0AB0
