hi Kenwei8011, the SFC0 will set the "static" DT time specified into function instance. So, no automatic time update is foreseen into SFC0, just force the PLC time to the SFC0, PDT parameter. Why not use updating with NTP? do you have CP443 card on your configuration? Regards

I think you need an OPC server into the SCADA that must exist in the PC directly connected to the S7-400, then using VPN , install an OPC client into the remote PC..It should works What kind of SCADA do you use? Wincc have it Alternatively use Teleservice http://www.automation.siemens.com/mcms/simatic-controller-software/en/diagnostics-options/simatic-teleservice/pages/default.aspx

for restart insert your code in OB100 in stand of SFB19 (it comes automatically recall each CPU restart)

I think you should use a TCP send/receive client/server configuration between them. In Telemecanique I have not experience.. in Siemens side you can use AG_SEND / AG_RECV (SFC5 SFC6). Moreover you need to define who's server and client, here follow a picture who show a sample of PLC Siemens working as server (define a TCP connection in NetPRO config, the add from the CPU a new connection and define it as "TCP connection") http://forums.mrplc.com/uploads/monthly_11_2013/post-51601-0-35734700-1383659067_thumb.jpg http://forums.mrplc.com/uploads/monthly_11_2013/post-51601-0-20592700-1383659089_thumb.jpg then define if Siemens C working as Client or Server by checking / not the flag http://forums.mrplc.com/uploads/monthly_11_2013/post-51601-0-14333300-1383659109_thumb.jpg and define your communication partner (Telemecanique ) (TCP port and address) http://forums.mrplc.com/uploads/monthly_11_2013/post-51601-0-47351200-1383659123_thumb.jpg the you have to defined a fixed data exchange size with Telemecanique PLC, and read/write it using AG_SEND or AG_RECV
