Greg_E Posts: 88 Rating: (2)	Hi Ladies and Gentelmen, i have to upgrade a system and export it's info through MB, i thought about doing it using MBUS_INIT, i know i can export through RS485(one of the serial ports on the PLC). i would like to know is there a posability to export info from S7-200 PLC's in ModBus protocol through CP-243-1 IT module that means MB on TCP/IP. Thanks in advance, Best Regards, Greg.
