Parameter details of control data (Output Assemblies)
Output Assemblies (Address 0, Bit 1 to Bit 7)
Handshake/Clear bit
Output Assemblies (Address 0, Bit 8 to Bit 11) Reading
start request/Each operation instruction
*1 When specifying a bank, specify "Address 2 Bank number"
*2 Preset data can be deleted by setting "1" for Address 5, setting "0xFF" for
Address 6 and then registering the preset data.
*3 Before starting tuning, specify "Address 2 Bank number".
If the bank number is illegal, a tuning error occurs.
Point Exclusive control of reading Start/each operation instruction
For reading Start/each operation instruction, priority is given to
the operation performed first. An error will occur if another
operation is performed during operation.
Output Assemblies (Address 1, Bit 0 to Bit 7) Completion
bit clear
* When Complete Bits are cleared, Error/Failure Bits of each operation are also
cleared.

List of error codes
Cyclic communication operation procedures
The SR-750 Series offers two trigger input measurement methods: "Level trigger"
and "One-shot trigger".
Refer to
"4-2 Timing Mode (Page 26)"
This section describes the SR-750 Series cyclic communication operation
procedures for each trigger input measurement method.
The following timing chart and operation descriptions use Output Assemblies
"Read Start Request" (Address 0 Bit 8) for read start instruction of the SR-750
Series. The procedure without handshake is used for description.

100 to 199 Command error
Values with 100 added to the "Command communication
response error code" (page 9-4) are applicable.
201 Reading error Reading failed.
202 Comparison error The read data did not match the preset data.
210 Tuning failure
The code could not be found within the field of view while
tuning.
213 Tuning failure Tuning was aborted.

Operation
instruction error
Another operation instruction was received during
operation. In this case, the incoming instruction is not
performed.
102 Bank number error
The parameter bank number specification is invalid.
Example: A number other than 01 to 16 is specified in
tuning operation.
220 Preset data error
The preset data specification is invalid.
Example: The specified preset data size is invalid when
preset data is registered.
230
EIP data update
error
Read data larger than the specified size in the cyclic
communication was received.
