TX_DLY 1005  1 to 500 

milliseconds 

 

TX DELAY—Configurable response-delay timer 
allows you to force the UDC to delay its response 
for a time period of from 1 to 500 milliseconds 
compatible with the host system 
hardware/software. This parameter is also used for 
the IR communications link.

Sample 
Periods 

 

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 ComSTA is set to MODBUS and if 
SHEDENAB is set to DISABL, Shed Time will not 
be configurable. 

SDMODE 1009   

 

SHED CONTROLLER MODE AND OUTPUT 
LEVEL—Determines the mode of local control you 
want when the controller is shed from the 
communications link.  

LAST 0 

LAST—SAME MODE AND OUTPUT—The 
controller will return to the same mode (manual or 
automatic) at the same output level that it had 
before shed. 

MAN 1 

TO MAN—MANUAL MODE, SAME OUTPUT—
The controller will return to manual mode at the 
same output level that it had before shed. 

FSAFE 2 

FSAFE—MANUAL MODE, FAILSAFE OUTPUT—
The controller will return to manual mode at the 
output value selected at Control prompt FAILSAFE.
