Example:
Command: T1R00090CR
sets cycle time to about 5 seconds
Response: TR00090CRLF
cycle time is about 5 seconds
To query the cycle time:
T1RQCR
7.5 DIGITAL INPUT AND OUTPUTS
To set the digital outputs and query the digital outputs and digital input:
M(a)(b)
M is the digital input output command
a is the I/O number as follows:
1 is output 1
2 is output 2
3 is input only, b must = Q
b is the command as follows:
O is output on (1&2 only)
F is output off (1&2 only)
Q is status query
Example:
Command: M1OCR
turn on output 1
Response: M1OCRLF
output 1 is on
Example:
Command: M1QCR
check status of output 1
Response: M1OCRLF
output 1 is on
Example:
Command: M3OCR
incorrect command digital input cannot be set
Response: .CRLF
response to incorrect command
7.6 ANALOG INPUTS
To read the analog input one input at a time
S(n)CR
S is the scan command
n is the loop number
The response is in degrees F for thermocouple inputs with resolution to 0.1 F. For all
other inputs on the millivolt scale the response is in percent of full scale with resolution
of 0.01%. A plus or minus sign follows the loop number.
