Micrologix1400 Ethernet to host comm
Micrologix1400 Ethernet to host comm
(OP)
I haven't done an AB Micrologix project for maybe 5 or 6 years now, and in fact my copy of RSLOGIX500 doesnt even support the 1400...updated software on order.
But after doing some looking around, reading AB manuals....fun eh?
What I have for this project is the Micrologix1400 connected to a host system via Ethernet. I need to run something on my PC to emulate the host, sending parameters to the program running in the 1400. Basically it will be some commands that are bit oriented..ie..turn on a light, motor, etc. Others will be numerical values such as weights of material. So is there some software package (freeware would be nice) that I can send data. That brings up the second part...how does the 1400 actually get data? Thru the MSG command? Sample programming might be helpful.
The other item I am controlling is over the RS485 and those are Powerflex VFD units (2 of them) where I need to send on/off and speed settings. Are there any doc's that describe how this interface works as well?
I've been immersed in Koyo programming for the last several years so I apologize if this is a simple question...

You don't need to write any code in the MicroLogix controller to accept messages from an HMI package. While I do recommend designating a specific data file to serve as the HMI interface memory, you don't have to write an "receive MSG" instructions or make any specific settings to data files. By default, all MicroLogix data files are read/write.
MicroLogix 1100/1400 via Modbus to PowerFlex 4-series drives is a standard feature of the "Connected Components" example set for RA. There will be examples in the RA Knowledgebase and there's a "Connected Components Accelerator" DVD with example code on it too.
I still prefer to have my Start/Stop hardwired to MicroLogix/SLC/PLC controllers because they don't have a true I/O connection over Ethernet like ControlLogix-family controllers do.

Changing the connection to static or BOOTP doesnt seem to make a difference.
Any thoughts?

Also enable or disable bootp will just enable/disable to ml1400 from broadcasting its mac id and ip(if set).

Thanks for taking the time to read and respond!
