Command Controls (41,022 – 41,022)
The command control word is used to control the unit. Each bit gives access to a
command or state as if the operator was using the keypad.
Bits initiating a command (7-12) must change state in order to cause the command the
begin. For example, to reset totalizer 1, Bit 9 must be set to 0, then changed to 1. It can
stay set or clear for any period:
Read/Write (R41,025 – R41,026) Total Decimal Places
Sets the number of decimal places (0-3) being read for Total 1, (words 41,016 and 41,017)
and Total 2, (words 41,018 and 41,019).
With 3 decimal places, the largest value that can be read is 2,147,483.648.
With 2 decimal places, the largest value that can be read is 21,474,836.48.
With 1 or 0 decimal places, the largest value that can be read is 100,000,000.
Example: R41,025
Bits 0 and 1 are used to indicate the number of decimal places being read in Total 1,
Words 7 and 8.
Bit 15 is used to indicate if the decimal place is too large to read the total value correctly.
