Sources and notes
- EMMXX Register table · version V1.0, 2019 manufacturer's register table for EMM-04S and EMM-04CS
- Currents are in mA, not A.
- Relays, digital inputs and outputs, pulse and alarm registers need the I/O model (EMM-04CS); the table marks which registers each model has.
- The alarm dynamic block (20500-20531), the alarm slot registers 17202 to 17328 (first register of each alarm) and the enumerated codes are not mapped. See the table.
- The table does not state byte or word order. Not tested on a device.
