5.3 Point Device Type Holding Registers
There are 2000 point device type holding registers. Each register address consists of two bytes (upper and lower) as defined in
representing two detectors or modules as shown in
. Devices
in the upper byte have even number points; devices in the lower
byte have odd number points.
