5 6 DIAGNOSTICS DATA TRANSMISSION
To readout diagnostics set the SW1 microswitch to configuration mode (see pt OPERATION MODE).
Correctness of transmission proceed on RS485 interface, can be checked by readout of the errors list by ADAConfig Software from
the module memory. Frames error counter will be increased, in case of: improper speed set compared to real speed of data
transmission. Parity error counter will be count the errors which can arise in case of misrepresent bytes in transmitted sign.
This counter will not work in case of disable control parity.
For checking this counters press the button [Read transmission errors], and to delete (zeroing of counters in the memory of the
module) press [Delete transmission errors].
In case of parity errors or frame errors check ADA-DIOC40 module's configuration and correctness connection of RS485 bus to
RS485/422 port of the module.
When diagnostic is finish, set the SW1 microswitch to RUN mode (see pt. OPERATION MODE).
6 COMMUNICATION MODES
The module can operates in one of three communication modes:
a/Signalling of DI status - after each change of the input status, the module sends an informing frame about that the master device,
b/Modbus – the module is working like device Modbus SLAVE type
c/Signalling of DI status and Modbus - the module is working in two above modes simultaneously - this required connection 4-wire
RS485 bus from the module to the master device.
6 1 SIGNALLING MODE OF CHANGE DIGITAL INPUT STATUS
In this mode Signalling of DI status – the module sends after each change of the input status, informing frame about that the master
device. Types of send frames ware described below.
When input status was changed from 0 to 1, the module will send the frame to control system in the form of a string of bytes [HEX]
40 64 02 01 00 9A AF
where:
0x40 – module address
0x64 – signalling function of change input status
0x02 – number of data bytes
0x01 – data1: current input status
0x00 – data2: previous input status
0x9A – checksum CRC16 -Low
0xAF – checksum CRC16 -Hi
When input status was changed from 1 to 0, the module will send the frame to control system in the form of a string of bytes [HEX]
40 64 02 00 01 5A FF
where:
0x40 – module address
0x64 – signalling function of change input status
11
ADA-DIOC40

0x02 – number of data bytes
0x00 – data1: current input status
0x01 – data2: previous input status
0x5A – checksum CRC16 -Low
0xFF – checksum CRC16 -Hi
Checksum CRC16 is countered from first byte (0x40) to last data bytes data2 (together with this byte).
enerating polynomial CRC16 (MODBUS) = 0xA001
