Hi all,

I'm planing to use ET200S as a stand alone PLC for a distance monitoring application.
I 'm currently facing two problems during hardware configuration.
A brief description of my setup:
slot 1-3: IM151-7 CPU 6ES7 151-7AA13-0AB0
slot 4: PM-E DC24V 6ES7 138-4CA01-0AA0
slot 5: 8 DO DC24V  6ES7 132-4BF00-0AA0
slot 6: 4 AI 2wire 6ES7 134-4GD00-0AB0

When I upload the hardware configuration to the PLC using MPI, the SF LEDs  on power module and the analog input card module are on. The error message for the analog input card says
: system is known and ok, but the part number cannot be read. I tried replacing the card without any luck.
Is it normal for the power module SF signal to be on? ( assuming no load on PLC)
Thanks alot for your help.

Hello,

What does it mean 'no load on PLC'? Did you wired those modules? It is not normal SF to be ON.

Best regards,

UMENCHO,

Thanks for your reply, By "no load" I mean nothing is connected to the I/Os. After I upload the harware configuartion, the cpu and digital module work fine (no SF and no error message in diagnostic buffer), only the analog card and power module light up.
