Hi all. I have a SIEMENS s7-224 XP CPU with two ports. On one port I have a Siemens touch panel TP177A and I have connected the other port to a PC via a PPI cable. I use S7-200 explorer to read some data logged on a memory cartridge on the PLC and it takes about 3-4 minutes to read a 10K file and during this time the values on the touch panel become #### which is as if communication between PLC and touch panel is lost. Any ideas why this is so slow and why touch panel freezes? Ports speed is set to 19.2kb
