Ethernet remote I/O master module for DL405 PLC
The Ethernet Remote Master H4-ERM100 connects D4-430, D4-440 and D4-450 PLC systems to slave I/O over a 100Mbps high-speed Ethernet link. Each ERM module can support up to 16 additional H2-EBC systems, 16 Terminator I/O EBC systems, or 16 fully expanded H4-EBC systems. Of course, combinations are fine, too.
The ERM connects to your control network using Category 5 UTP cables for cable runs up to 100 meters. Use repeaters to extend distances and expand the number of nodes.
The PLC, ERM and EBC slave modules work together to update the remote I/O points. These three scan cycles are occurring at the same time, but asynchronously.
It is recommended that critical I/O points that must be monitored every scan be placed in the CPU base.
- Master Ethernet remote I/O on a 10/100Base-T network
- Can be installed in a local base, when a D4-430, D4-440 or D4-450 is used as the CPU, or in a local expansion base (D4-450 based system only)
- Ethernet cable connects to H2/4-EBCs directly or via Ethernet hub(s)
