Will spend some time exercising all possible software settings options and report back. Best of all, this cable is commonly (and cheaply!) available in the aftermarket. Allen-Bradley uses this cable with their RSLinx comm software to communicate with SLC and ControlLgix PLC’s.

Aunque los M221 integran la funcionalidad Serial IO Scanner, en esta ocasin usaremos las funciones estndar de comunicacin Modbus: READVAR, WRITEVAR y WRITEREADVAR. En esta entrada comentaremos la comunicacin Modbus RTU a travs del puerto serie integrado SL1 por RS485. This is a symmetrical null-modem cable where DTR is sent across to DSR and DCD, and RTS is sent across to CTS. Comunicacin Modbus RTU entre Schneider Modicon M221. A - 1 Safety Instructions Please read the instructions carefully before using the equipment.
While the Startech (Chinese) general-purpose null-modem cable was lifeless, I do see incoming traffic on the CMM311 using an Allen-Bradley 1747/1756-CP3 cable (DB9F-DB9F) with a DB9M-DB25M straight adapter. (Modbus-RTU Protocol) General-Purpose Interface AC Servo 1CW822 MR-J4-A-RJ INSTRUCTION (MODBUS-RTU) B B. On the New Device page, leave all the default values and type in the following fields: Name: Modbus Hostname: type the IP address, for example 10.20.8.117. In this example well select Modbus TCP, and click Next. Specifically, the GE cable ties the CMM311’s DTR back to the PC’s CTS, and does not use the CMM311’s RTS signal at all. Modbus RTU (only available if the Serial Support Gateway module is installed) Connects to a device via Modbus RTU over serial. However, the GE docs do show a pinout diagram which indicates non-standard use of hardware handshaking. The recommended GE !C690CBL702 unit is obsolete, and barely mentioned in the aftermarket (only offer price $350!).
