Note: PDS-100 accommodates up to 31 addressable units.
Command Mapping
Single bit read and write. Set bit to initiate action, PDS-100 will clear bit upon execution
Coil 0 = "start" > Pump A – (all configurations except individual – individual pump A only)
Coil 1 = "stop" > Pump A – (all configurations except individual – individual pump A only)
Coil 2 = “start-2" > Pump B – (individual configuration only)
Coil 3 = "stop-2" > Pump B – (individual configuration only)
Single bit status, read only
Input 0 = "busy" > Pump A – (all configurations except individual – individual pump A only)
Input 1 = "error” > Pump A – (all configurations except individual – individual pump A only)
Input 2 = "busy-2" > Pump B – (individual configuration only)
Input 3 = "error-2" > Pump B – (individual configuration only)
16 bit word read and write. Not allowed to change when pump is busy
Holding Register 0 = "rpm" > Pump A
Holding Register 1 = "stroke count" > Pump A
Holding Register 2 = "rpm-2" > Pump B
Holding Register 3 = "stroke count-2" > Pump B
16 bit word information read only
Input Register 0 = "configuration" *see configuration table
Input Register 1 = "operating mode" 0=continuous, 1=dispense
Input Register 2 = "operating mode-2" 0=continuous, 1=dispense
Input Register 3 = "error code" 0= no error, 1= error
Input Register 4 = "error code-2" 0= no error, 1= error
Input Register 5 = "minimum-speed"
Input Register 6 = "maximum-speed"
