Integers are unsigned, 16-bit values. Floating point values are IEEE 754 32-bit floating point values.
The default Modbus order is Low Word-High Word. The order can be changed in the Communications Menu.
The default serial data format is: 9,600 baud; 8 data bits; no parity; 1 stop bit.
NOTE: Avoid continuous writes within loops. Excessive writes to the EEPROM will cause premature EEPROM failure. The EEPROM is
rated for 1,000,000 writes.
Underlined parameters are not accessable using a remote user's interface (RUI) or the controller's front panel. They can only be ac-
cessed using communications.
*Some of the parameters are not functional in some configurations of each model. Check the user's manual for information.
