My way of controlling this PLC is this. Controller 1 (as Master - either "DP Master or PN Master") - ET200M is configured in controller 1. - The sequence is saved in controller 1 and the I/O from the other controller will be added on your sequence. It's up to you what logic you want. - Recipient of data from controller 1 (you must use send/receive blocks DPRD_DAT(SFC14) to receive the data "in your case the I/O of controller 2" Controller 2 (as Slave - either "DP Slave or PN Slave") - Controller 2 has to send data using DPWR_DAT(SFC15) to controller 1 Click this Master-Slave configuration for DP Note: slaves can also write on the master, not only read. |
