The first control character indicates the beginning of a data transmission:
1)
? Hexadecimal 3F / character for data query
If the control receives a ’?,’ requested information (Program Instruction,
Parameter, Status Message, Variable, Logic Task, Cam) is output.
2)
# Hexadecimal 23 / character for transmission of data
If the control receives a ’#,’ the following characters are saved into the
control (NC, Parameters, Logic Task, Variables, Cam).
3)
! Hexadecimal 21
If the control receives a ’!,’ the following characters are picked up as the
control command.
4)
: Hexadecimal 3A
Colon for polling query.
s This character identifies the station number. The ’s’ is to
be replaced by an appropriate character, depending on the operating
mode.
1) In RS232C operating mode, the ’s’ is replaced by a blank space.
However, the responses always contain the station number.
2) In RS485 mode, the ’s’ is replaced by the respective station number
(1 - 9 ; A...W for No. 10 to 32). If this number does not correspond to
the number set in the programming module, there is no response to
the received data.
If ’s’ is a blank space, this information is relevant for all users on the
bus.
The third character identifies the information type:
1)
N Hexadecimal 4E / character for NC instruction.
The information following the ’N’ is interpreted as an NC program
instruction.
2)
K Hexadecimal 4B / character for parameter.
The information following the ’K’ is interpreted as a parameter.
3)
X Hexadecimal 58 / character for status.
4)
P Hexadecimal 50 / character for Logic Task.
The information following the ’P’ is interpreted as a Logic Task instruction.
5)
V Hexadecimal 56 / character for variable.
The information following the ’V’ is interpreted as a variable.
6)
C Hexadecimal 43 / character for a command.
The information following the ’C’ is interpreted as a command.
