MicroLogix Remote Packet Support
Series D MicroLogix controllers and all MicroLogix analog controllers can respond
to communication packets (or commands) that do not originate on the local DH-485
network. This is useful in installations where communication is needed between the
DH-485 and DH+ networks.
The example below shows how to send messages from a PLC device or a PC on the
DH+ network to a MicroLogix 1000 controller on the DH-485 network. This
method uses an SLC 5/04 processor bridge connection.
When using this method:
•
PLC-5 devices can send read and write commands to MicroLogix controllers.
•
MicroLogix 1000 controllers can respond to MSG instructions received. The
MicroLogix controllers cannot initiate MSG instructions to devices on the DH+
network.
•
PC can send read and write commands to MicroLogix controllers.
•
PC can do remote programming of MicroLogix controllers.
