Holding register 0x0109: Communications watchdog timer (ModScan32 address:
40265)
0 to 999.9 seconds in BDC format. For example, a register value of 0x0150 provides a
watchdog time of 15.00 seconds
Holding register 0x010A: Response timeout count (ModScan32 address: 40266)
This register specifies the SPI Response Timeout in milliseconds
A 2 Modbus/Nanoline communication
The ModScan32 request address range is shown in decimal only. The ModScan32
software does not start its addressing at 0 so all decimal ranges shown are offset by a factor
of one, i.e. hexadecimal 0x1000 is the equivalent of decimal 4096, but because of
ModScan32 addressing, the starting address is actually 4097. If using ModScan32 in the
hexadecimal format, then hexadecimal 0x1000 actually equals 0x1001.
