S7/WAGO Configuration

S7/WAGO Configuration

S7/WAGO Configuration

(OP)
Hi

I currently have a system which comprises a S7-314C-2 DP which is link to a number of SEW drives & 2 WAGO I/O units this system is now commisioned succesfully and all is fine other than because of time delays between the PLC and the remote I/O I need to speed up the response time of some of the control. To acheive this I have replaced one of the WAGO Fieldbus modules (740-343) with a WAGO Fieldbus controller module (740-833) and I have programmed the controller so that the process can be controlled locally. this in principle appears to work, other than there appears to conflict between the I/O, as far as can establish I beleive this due to how the WAGO hardware is configured, i.e the hardware has to be configured so that the fieldbus controller can control the I/O and not the S7 PLC and then the S7 PLC I/O has to be mapped locally in the WAGO unit to access the local I/O. This all appears fairly straightforward other than the information as how to configure the S7 to communicate with the WAGO is lacking, reading through their manual the only comment is 'In Preparation'.
Am I right in thinking that I need to use Siemens FB SFB52 (RDREC) & SFB53 (WRREC) to communicate with the WAGO unit?
Any assisitance will be greatly appreciated

Hi

thanks for the response, I already have this document, the issue has now been resolved having spoke to a very helpful Derek Lane at WAGO, as originally thought it was purely a case of getting the configuration correct.
again thanks for your help
