Trying to talk with an Atam 4018 analog module. This module does not have modbus, only asc. 9600 baud 8, none, 1. I write using a edge contact. Success of the write turns on the receive on the very next rung. Write then read, the read misses the first 3-4 characters at 9600 baud. If I go to 1200 baud I can get the first characters. I can not find a delay on Send on the Adam. 9600: "2.50 " 1200: " >+22.50 " Is there something else I can try to get the first part at 9600 baud? Thanks Brad { "data-align ": "none ", "data-size ": "large ", "data-attachmentid ":106487}

9600: "2.50 "
1200: ">+22.50 "

You need at least a one scan delay between the read/write and vice versa. It is possible that it might need more than a single scan.

Darn luck. This Is what i thought. Now if I could ever get an answer from Advantech to see if the Adam can have a delay before sending response.
