Hello All,
I am using a SIEMENS S7 TCP-IP DRIVER to communicate with S7-1200 PLC (ZENON SUPERVISOR) . I am having 3 S7-1200 PLC. PLC1 has 424 tags, PLC2 has 381 tags and PLC3 has 2333 tags. I am facing an issue with the SCADA - PLC Communication Reconnection when the PLC3 [FONT=verdana, sans-serif][SIZE=2].
Case 1
When I Close my runtime and open again, the SCADA establishes communication immediately with PLC3.
Case 2
When I use STOP/START Driver Function my SCADA-PLC Communication reconnection is immediate. with PLC3.
Is it because the PLC3 tag has a high percentage of variables it takes so much time to reconnect?
Kindly let me know what might be the cause for the issue and a possible solution for the same. Thanking you in advance.
Regards,
