timeEVT
N/A Delay Time Option
This opcode will turn ON or OFF a specified event for the specified amount of time.
The Delay Time is the time in seconds. The range is: 0 – 500.
The Option is the event to turn ON or OFF. The options are: Event 0 ON or OFF – Event 31 ON or OFF.
TOD_INQ
N/A N/A Time
This opcode is a time of day inquiry that would be used to start a process or subroutine at a specific hour
and minute.
The Time is the time to check, in Hours:Minutes format. The Hours range from 0 – 23, and the Minutes
range from 0 – 59.
TZ_INQ
Temperature Level N/A Option
The zone temperature inquiry is used to wait for the actual control zone temperature to reach the value
specified.
The Temperature Level is the specified level to wait for. The range is -301 (disable) – 30000.
The Option is the wait options: Wait, Wait Up, or Wait Down.
The default band can be set under the Configuration Menu and is typically 15 degrees. The band limit can
be changed by the S ET_WAIT opcode.
The LIMIT opcode immediately following this opcode sets a time limit on the wait. A BRANCH opcode
immediately following this opcode can be used to change the program flow based on the inquiry results.
This opcode is identical to the TC_INQ opcode, except that it will deal with zones.
Z_SETPT
Temperature Setpoint Atmosphere Setpoint Option
This opcode is used to set the temperature or atmosphere set point for a zone.
The Temperature Setpoint is the setpoint to send for the temperature process variable. The range is -301
(disable) to 30000.
The atmosphere Setpoint is the setpoint to send for the atmosphere process variable. The range is -0.01 to
99.99.
The Option will wait for the setpoints to be reached: Blank (Don’t Wait), Wait, Wait Up, or Wait Down. Note –
The Blank option is an actual blank line, not the word “Blank” .
ZONE_OFF
Temperature Value Atmosphere Value Zone
The Zone Offset opcode is used to set a temperature or atmosphere offset to be added to the set point sent
to a specific zone. The same loop (furnace) can have different offsets for each zone. The zones must be
defined in the zone configuration.
For example, a pit furnace has three zones: top, middle, and bottom.
The zones could be defined as:
•
top = zone 1
• middle = zone 2
• bottom = zone 3
If the ZONE_OFF opcode is used in a program with Temperature Value = 50 and Zone = 1 and a setpoint of
1700, then:
• A set point of 1750 would be sent to the top zone (Zone 1)
• A set point of 1700 would be sent to the middle zone (Zone 2)
• A set point of 1700 would be sent to the bottom zone (Zone 3)
