7.0 COMMAND STRUCTURE
Communication between the ANAFAZE 8 PID and the host computer is accomplished
with ASCII code. The baud rate can be selected from 300 to 9600 baud. Please see the
hardware section of the manual for baud rate selection and interface description.
The following ASCII formats are used:
1. ASCII CAPITAL letters are always used.
2. All commands and responses are terminated with an ASCII carriage return (CR).
3. The first command in any sequence must select the controller for
communication; after that all commands will be accepted and can operate on the
unit selected. If a unit is not selected there will be no response to any command
sent from the computer.
4. The ANAFAZE 8 PID will never initiate communication.
5. The ANAFAZE 8 PID response ends with a carriage return and a line feed (CR
LF).
6. Commands that are not accepted by the ANAFAZE 8 PID will be answered by a
period followed by a carriage return and line feed. There will be no answer
unless a controller is selected.
7.1 CONTROLLER SELECTION
B(ab)CR a is the controller group select 1 or 2
b is the controller number 0 through F
To provide for selecting 32 controllers on one communication line ASCII codes 0 to 9
and then A, B, C, D, E, and F are used to select up to 16 controllers in each group.
Example:
Command: B10CR selects controller 10 (normally first controller)
Response: B10CRLF
7.2 ANALOG INPUT TYPE AND CONTROL SETPOINT
Input Channel type and setpoint:
C(n)(t)(abcd)CR C is the channel input indicator
n is the loop number from 1 to 8
t is the type per the following table
abcd is the setpoint, 0 to full scale
