Applies To:
  • CitectSCADA 5.xx
Summary:
The existing S7PTP driver does not work with two Siemens CP340 in the same rack. 

Solution:
A new Function Block (FB12) has been developed by CI Technologies which allows for 2 x CP340s to be used in the same PLC rack. Contact Citect Customer Service for more details about the new FB and associated blocks.

To use a second CP340 in the same rack for an S7-300 PLC, the following S7 blocks are required:

i. FB12

ii. DB123, DB124

iii. T126

FB12, DB123/DB124 are supplied free by CI Technologies.
