1)
If the optical interface is required you shall order the following: 11th position 4 (FMS) or L0A (DP) and additionally:
For single ring: SIEMENS OLM 6GK1502-3AB10, for double ring: SIEMENS OLM 6GK1502-4AB10
The OLM converter requires an operating voltage of 24 VDC. If the operating voltage is > 24 VDC the additional power
supply 7XV5810-0BA00 is required.
