4 Extended operating hour counters via MODBUS
The operating hour counter and the overload hour counter are available via
the Modbus Interface. The maximum range was extended to 1,193,046
hours in CM-Software version 1.2.1.
At the Modbus register addresses MW124 and MW125 the existing operat-
ing hour counters are still available to ensure compatibility. These operating
hour counters are showing up to 65,535 hours.
The new register addresses for the extended operating hour counter:
Low word: MW 130
High word: MW 131
The new register addresses for the extended overload hour counter:
Low word: MW 132
High word: MW 133
The data type used at these registers is unsigned integer of size 16 bit.
To use the extended operating hour counter, connected systems must con-
catenate two Modbus register addresses in the following way:
LW
HW
MW 130
MW 131
OpHour [h] = (( x 65536) + ) / 3600 LWHW
This procedure is also applicable for the overload hour counter:
LW
HW
MW 132
MW 133
OverloadHour [h] = (( x 65536) + ) / 3600 LWHW
