Appendix 1: PGA 3510 Common Modbus Registers 

 

This appendix covers Modbus registers most commonly accessed by PGA 3510 users. These are Modbus 

registers 200 through 227 and their descriptions. There are other Modbus registers used by the PGA 

3510. If you need information on other registers, call SSi at (513) 772-0060.

pump_run_min 

The total time in minutes that the 

pump has run since the last time 

memory was cleared or a manual 

reset took place. This value, plus 

pump_run_wks, will provide the total 

amount of time the pump has been 

running. When this number reaches 

10080, pump_run_wks is increased by 

1, and pump_run_min is reset to zero.  

215 

pump_run_wks 

The total time in weeks that the pump 

has run since the last time memory 

was cleared or a manual reset took 

place. This value, plus pump_run_min, 

will provide the total amount of time 

the pump has been running.

pump_run_now 

The time in minutes that the pump is 

running (reset to zero if pump is 

turned off). Maximum value is 30000. If 

pump_run_now is greater than 

pump_run_max, then pump_run_max 

is set to pump_run_now. 

218 

pump_run_max 

The longest time in minutes of a pump 

session. If pump_run_now is greater 

than pump_run_max, then 

pump_run_max is set to 

pump_run_now.
