Reading The Error Counters
The entire packet of all 18 error counters may be read by issuing MODBUS command to
Register 0x040 with a register count of 18. The sequence of registers is according to the error
number in Table 1 in ascending order.
Each register is a 16-bit word. If the most significant bit is set to a logical one, this indicates
that there is an active error residing in the Status stack.
The remaining 15 bits indicate the number of errors that occurred since power was applied to
the unit.
The user may clear all error counters by issuing Function Call FC5 coil #6.
