E300 HMI to S7 200

grunt Posts: 3 Rating: (0)	Hello, I wish to connect a Mitsubishi E300 HMI to an S7 200 by using the RS422 port on the E300. This allows me to keep the HMI RS232 port free for use in transparent mode. What lead do I require? I am aware of this one but it is for RS232/RS485 not RS422/RS485: 6ES7972-0CA10-0XA0 I'd be grateful for any advice. Thanks in advance. Grunt.

Good luck
