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.
