Daisy Chain – Maximum Number of Connected Modules
Prerequisites:
l
Optimized network
l
Only DMA-EZCCM-001 modules in the daisy chain, no additional switches, no third-party devices
l
Exchange of pure process data, no acyclic data
l
Cable length between the DMA-EZCCM-001 modules max. 50 m
l
Power chain is not reaching 4A
Cycle time
Maximum number of DMA-EZCCM-001 modules
1 ms

Depending on the amount and type of DataMan Readers connected to DMA-EZCCM-001the 24VDC chain might be
reduced. Ethernet chain can continue as per specifications above.
The figure below shows a concept of multiple 24VDC chains, and maintaining a single Ethernet chain:
