 Posted: 06/01/2021 11:29 Post subject: [Siemens CPU 1517H-3 PN] Redundancy - Fiber Optic |
 |
|
Hi there,
Is it possible to use two S7-1517H PLCs without fiber optic ?
In my current project, I need to integrate two S7-1517H but I haven't received yet the fiber optic connectors.
In the meantime, for testing purposes, I'm wondering whether I can still do either of the following :
1- downloading a program to each individual 1517H plc ?
2- establish redundancy with copper ethernet cable ?
3- establish redundancy with only one fiber optic cable ?
Thanks in advance for any advice |

You can use without problem.
Just disable SYNCUP RH_CTRL instruction for not getting error and you can test each one PLC.
Do not forget to enable afterward.
