Communication station configuration

...

  • Communication protocol: ALYA Lubrikacie.
  • The station address is an address of the control station for the communication over RS485 bus. The address is a one-byte value.
    Note: commonly used station addresses (A, B, C...) must be configured as their ASCII codes, i.e. 65, 66, 67 ...


Station protocol parameters

Communication station - configuration dialog box - "Protocol parameters" tab.
They influence some of the optional parameters of the protocol.

AddressMeaningValue typeRead/Write
RNNew weighted roving. After weighting and printing the weight ticket, the application writes a text string into the I/O tag in the format:
ID;CV;VZ;POC;ZD;

where:
  • ID - identification number of weighting. Autoincrement integer [1, 2, 3, ...].
  • CV - number of scale [1, 2].
  • VZ - preparing from the outside in meters, integer.
  • POC - number of unspool cycles [0, 1, 2].
  • ZD - including into the line. Integers separated by blank space. The first number means a priority line, the second one, and others represent the alternative lines, e.g. 7 5 6.
Example of written value: "5247;2;60;1;6 4 5;"		TxtOWrite

The number of spools on the lines. The I/O tag is in the format "C1;C2;C3; … Cn;", where Ci represents an integral number that indicates the number of spools on line i.
Example: "626;42;0;78;562;489;28;55;"		TxtIRead
NCReset the counters of spools on the lines. Write any valid value, to reset the counters. The control unit will send a message in the format "C1;C2;C3; … Cn;", where Ci represents an integer number that indicates the number of spools which were included on line i since  the most recent information on the number of spools was sent (see PC).
This message will be set as a new value of the I/O tag with the NC address.		TxtOWrite
