The PacDrive LMC Pro is equipped with a NetXchip communication processor onboard which can be operated with two independent field bus protocols. Only one Ethernet field bus can be used. Through the two optional module slots of the PacDrive LMC Pro, further field buses can be used. They can be equipped with the optional modules OM-P, OM-C and OM-NE.
The OM-P and OM-C option modules do not have their own communication processors. When using OM-P or OM-C, the communication channels on the internal communication processor are used for this purpose. On the other hand, the OM-NE does not use the internal communication processor as it has its own communication processor.
The restriction of only two loaded fieldbuses on the internal communication processor is consequently not resolved by using the OM-P or OM-C modules.
The following field bus combinations are possible:
| Combination | Onboard | Option 1 | Option 2 | ||||
| LMC x00C | OM-P | OM-C | OM-NE | OM-NE | |||

In this way, the PacDrive LMC Pro can, for example, be used with the following field bus combinations:
Combination 1: one PROFIBUS onboard with a second PROFIBUS (option 1) and an Ethernet field bus (option 2)
Combination 5: one PROFIBUS and one Ethernet field bus onboard with two other Ethernet field buses (option 1 and option 2).
Option 1 and option 2 can be implemented either by the optional controller module on the right or on the left.
