How can I configure this instruction?example: I want to send the next command to the Ultra to enable de drive: 3A0007010DThanks and regards [/INST] You may send commands to Ultra 3000 using Host Commands.RS-232 port should be configured to use ASCII. The host language is not so easy to use from inside a PLC... anyway there are some docs and an example for SLC controller, it should work also with Micrologix, just it should be *converted* and checked for some conversion errors...:smileysad: Aid 22657 contains all this stuff.Start taking a look to Host Command Reference Manual Hope this helps… - fuzzy logic \\n </s>
