Messaging from MicroLogix 1100 to CompactLogix
firejo posted a topic in Allen Bradley / Rockwell Automation
Hey all. I’m trying to message from a MicroLogix 1100 to a CompactLogix. I’ve created the SLC mapping but when I execute the message instruction I get the error: “Error code (in upper byte of MGx:y.22) was returned by Comms module or CIP device”. I’ve never seen that before and I don’t know where to go from there. -
Configuring a 1761-NET-ENI
firejo replied to bfabling's topic in Allen Bradley / Rockwell Automation
Data-Linc Group makes a device that can be used in place of the NET-ENI and is much easier to setup. It’s the NET620. They also have a radio modem that has the NET620 functionality built in so if the device is located remotely you can make the connection wirelessly and still do the Ethernet to DF1 bridging. -
There are a couple of companies that make solutions to either extend or remotely locate I/O. I like the FreeWave solutions. They are Modbus RTU devices and can be done wirelessly or via a direct serial connection and operate via RS232 (or RS485).

Installing RSLogix 5000 on Windows-7 Ultimate
firejo replied to rajsiyer's topic in Allen Bradley / Rockwell Automation
Install VMWare on the PC and setup a Windows XP in VMWare. You can then install all the Rockwell software you want inside the XP machine (inside the Windows 7 machine) and it will work flawlessly. http://www.vmware.com/products/player/overview.html -
Freewave technologies has a wireless I/O product line that uses Modbus RTU. If you’re using the MicroLogix (anything but the 1000) it can be configured to be a Modbus RTU master (channel 0) and if you’re going to use the Compactlogix you would need the 1769-SM2 module which will give you Modbus RTU master compatibility. I’ve done it with both using the Freewave I/O and they both work well however the Micrologix (I’ve done it with the 1100) is a lot easier to setup. You can find info on the Freewave I/O here: http://www.freewave.com/Products/PRODUCTFAMILY/IO.aspx

MicroLogix and Wireless IO
firejo replied to mhowasso's topic in Allen Bradley / Rockwell Automation
I’m not sure if it’s too late for your needs but Freewave technologies has a wireless I/O product and it’s an Encompass partner approved product line. You can find it here http://www.freewave.com/Products/PRODUCTFAMILY/IO.aspx I’ve used them and they work very well. You will need to set up the port as a Modbus RTU port but the Micrologix 1400 (and 1100) ports will do this. They also have some write-ups on how to configure the PLC to work with the I/O radios (addressing etc…)
