I just want to ask if my CPU 315-2 PN/DP can communicate via Modbus TCP.

Thanks Experts.

Thanks for the help sir. Im confused because I saw a configuration on a modbus network where it used a CP 343 Lean.

There is also info about OpenMODBUS/TCP PN CPU.

Check it there again.

Hi Daniel,
there are 3 modbus packages:

  • OpenModbusTCP CP for CP343-1 / CP443-1
  • OpenModbusTCP Red for H-Systems or Single-CPUs with 2 CPs (for redundancy) and
  • OpenModbusTCP PN CPU for PN-CPUs
All of these products have the same modbus functionality, but they are for different hardware.
