Hello Graham; SFC 12 "D_ACT_DP" is available to deactivate and re-activate Profibus-DP slaves in Simatic Manager. How do you switch off (decouple) a slave without causing an error entry to appear in OB 86/OB 122? Enabling a disabled DP slave with SFC 12 'D_ACT_DP' There is no such SFC specifically for Profibus-PA instruments, but the DP/PA link (as a Profibus-DP slave) could be removed temporarily from the DP network while calibration activities are being done.; no instruments coulb be read from the PA side during the de-activation of the DP/PA link, but you would not get flooded with error messages. See if you can use iot in your PCS 7 installation. Hope this helps, Daniel Chartier |
