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.

1 2 ... 31 32 33 34 35 36 37 38 39 40 41 ... 54 55
