Commands for the integrated PID-controller
Set point: AAXsXXXX XXXX = 4 hexdigit for setpoint (°C x 10) selectable in the
boundaries of the partial range
Proportional band:
(„gain“ = 100% / Xp) AAXpXXXX XXXX = 4 hexdigit for 0001 ... 2710
respectively: 0.1 ... 1000.0%
special case: XXXX = 0000  gain  (2-point-controller)
XXXX = 8000  no Proportional control
Reset time:
(Integral time) AATiXX:XX
AATiXX.XX or
XX,XX Ti-time in format min:sec XX:XX is equivalent to 00:01 ... 99:99
calculation is every second
Ti-time in Format XX.XX sec is equivalent to 00.01 ... 99.99
calculation is every 10 ms
special case: 00:00 or 00.00 no integral control
Derivative time:
(rate time) AATdXX:XX
AATdXX.XX or
XX,XX Td-time in format min:sec XX:XX is equivalent to 00:01 ... 99:99
calculation in interval of the Td-time
Td-time in format XX.XX sec XX is equivalent to 00.01 ... 99.99
calculation in interval of the Td-time
special case: 00:00 or 00.00 no derivative control
Output delimitation: AAYxXXXX XXXX = 4 hexdigit for 0001 to 03E8 XX is equiv. to 0.1 ... 100.0%

AAYsX Output: 0000 ... 03E8 is equiv. to 0 ... 100.0% automatic mode
8000 ... 83E8 is equiv. to 0 ... 100.0% hand mode
XXXX = hexadecimal for 0000 ... 03E8 is equivalent to 0 ... 100.0%
(enforces hand mode!)
X <> 0 reset to automatic mode.

AARsX Output: XXXX hexadecimal-Byte
Bit 15 = 1 controller active
Bit 8 to 14 not used
Bit 4 to 7 = 1 internal use
Bit 3 = 1 Td = 0  no D-control
Bit 2 = 1 Ti   no I-control
Bit 1 = 1 gain = 0  no P-control
Bit 0 = 1 gain   on/off controller
X = 0 or 1  deactivates / activates the controller

Additional instruction for the RS485 interface:
Requirements to the master system during half-duplex operation:
1. After an inquiry, the bus should be switched into a transmission time of 3 bits
(some older interfaces are not fast enough for this).
2. The pyrometer's response will follow after 5 ms at the latest.
3. If there is no response, there is a parity or syntax error and the inquiry has to be repeated.
After receiving the response, the master has to wait at least 1.5 ms before a new command can be entered.
