E SR-750 UM

Cyclic communication data assignment

Data assignment during cyclic communication is performed as follows.

Result data (Input Assemblies)

Input Assemblies is a device that write responses from the SR-750 Series to the
PLC.
When using this device, each device function is assigned as follows.
Device status, Result Data, etc. are written to the Input Assemblies.

Gray parts are reserved areas for the system.

Control data (Output Assemblies)

Output Assemblies is a device that write instructions from the PLC to the SR-750
Series.
When using this device, each device function is assigned as follows.
Output Assemblies performs device control instructions, error clear, handshake
process, etc.

Parameter details of result data (Input Assemblies)

Input Assemblies (Address 0, Bit 0 to Bit 7) Handshake
and error status

* Handshake is a communication procedure to make the permission system for

read data writing.

Input Assemblies (Address 0, Bit 8 to Bit 13) BUSY status

Input Assemblies (Address 1, Bit 0 to Bit 7) Completion status

*1 This Bit also turns ON when the character string of "ERROR" is output when

reading error occurs.

*2 This returns to 0 when turning the applicable clear Bit ON or at next operation.

Important

After "1 Preset Reading Complete", "2 Preset Data Registration
Complete" or "3 Tuning Complete", wait 5 seconds or more and
start reading operation. If reading operation starts before 5
seconds elapse, it does not operate normally.
