Identifying code 250 lets you monitor or make selections for:
• Tuning Parameter Set #1 or #2
If Tuning Sets selection is "two keyboard" code 172 = 001
• Local Setpoint #1 or #2
If "2 Local Setpoints" is selected 131 = 0, 173 = 1
• Run or Hold Setpoint Ramp or a Setpoint Program Data
If SP Ramp or SP Program is enabled 178 = 1 Program, 178 = 2 Ramp
Table 5-12 is a table of numbers that could be returned by the UDC2300
controller. When a Read is requested for this I.D. code (250) you can
determine which parameters are active from this table.
To Write information to the controller, select what parameters you want
from Table 5-12 and enter the associated number in the data field of the
Write request.
For example:
Suppose you want to change from TUNING SET #1 to TUNING SET #2
while maintaining LOCAL SETPOINT #1 and SP RAMP STATUS =
HOLD.
READ 250 response is 00 or 02
WRITE 250 (07)
READ 250 response is 018
Note: Some of the numbers are Read only.
