DOK-CONTRL-CLM01.4LAP1-FK01-EN-P
With help from the RS485 bus system, up to 32 CLM controls can be
connected to a PC with the appropriate interface.
In this case, the PC is defined as the master device and the connected
CLM controls as slave devices.
The station number of each CLM is input into the CLM via parameters.
For all data transmissions, the station number is also transmitted.
For the transmission of or request for information, the station number is
input after the first control character instead of the space character. For
the station number, values between 1 and 32 are allowed.
For station numbers 10 to 32, a letter is input, according to the following
list:
Station No. Transmit Value
1 1
2..9 2..9
10 A
11 B
12 C
13 D
14 E
15 F
etc., through
32 W
Example for Station No. 10 (Hex = A):
Request to the CLM:
? A N 0 0 0 0 C R L F
Response from the CLM:
# A N 0 0 0 0 _ I n s t r u c t i o n C o n t e n t s C R L F
For further information, see description for Parameters B002 and B003.
The data transmission format for the serial interface is set in Parameters
B002 and B003. Here, it is also determined whether the interface
operates as a data interface or as an interface to the decade switch unit
’IDS01.’
