SHEDTIME
0 to 255 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
ODD
EVEN
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
