Programmable controller PI 6000
44
8 UPP  data format (Universal Pyrometer Protocol)
Data is exchanged between both the controller and the PC as well as between the controller and the meas-
urement pyrometer in 7-bit ASCII format with the following transmission parameters:
8 data bits, even parity and 1 stop bit (8,e,1)
The unit replies to a command with: Output (e.g. the value measured) + CR (Carriage Return,
ASCII 13), for commands that only involve entries with "ok" + CR or in
the case of an error with "no" + CR.
Every command starts with the 2-digit unit address (for PI 6000 always "C0", upper case "C" and digit "0"),
followed by 2 letters for the command (e.g. "ms" for value measured). The ASCII parameter or parameters
"X" then follow. Without a parameter, the unit replies with the parameter currently set.
The controller is "transparent" for almost all commands with the pyrometer's address, i.e. it sends these
commands to the pyrometer and the replies back to the PC. An exception is the “ms“ command, which is
always answered by the controller. The reason for this situation is the interfering provision of data when the
program is running with the online graph enabled.
Example: Entry: “00ms“ +
<CR>
The actual temperature measured by the pyrometer with the address 00 is returned
Reply: “07568“ +
<CR> signifies 756.8 °
Note: Negative temperatures are given in the ms commands as ´-0995´ for -99.5 °,
for hexadecimal values in 2s complement

pyrometer C0ezX X = 0...6 The pyrometer’s response time is increased by:
0 = nothing 1 = 0.01 s 2 = 0.05 s 3 = 0.25 s
4 = 1 s
5 = 3 s 6 = 10 s
