Parameter

Definition

SHED TIME— The number that represents how many sample periods there will be before the controller sheds from communications. Each period equals 1/3 seconds; 0 equals No shed.

Note: If ComSTATE is set to MODBUS or MB3K and if SHEDENAB is set to DISABL, Shed Time will not be configurable.

PARITY pertains to the use of a self-checking code employing binary digits in which the total number of ONE's (or ZERO's) in each permissible code expression is either ODD or EVEN.

Fixed at NONE when ComSTATE = MODBUS ODD PARITY

EVEN PARITY

BAUD RATE is the transmission speed in bits per second.

DUPLEX— Transmission Type

HALF DUPLEX— Two wires

FULL DUPLEX— Four wires

ATTENTION

When the Auxiliary Output/RS422/485 Option board is installed, this selection is fixed at HALF.

Defines word/byte order of floating point data for communications.
