Omron FQM1-MMA21 Synchronous Data Link Bit Area, Ladder execution results data, Transfer time

Synchronous Data Refresh Section 5-4

Synchronous Data

Normal (via Ladder)

Counter 1 values

Counter 2 values

Pulse output 1

Pulse output 2

Analog input

Analog output 1

Analog output 2

Inner I/O input (Built-in input)

System Setup Select Synchronous Data

Set in upper 2 words

System Setup Select Synchronous Data

Set in lower 2 words

4 words of data transferred for each Module

Example: 4 words of data sent by Motion Control Module #1

+0	Counter 1 values
+1		Transfer
+2	Pulse output 1
+3

Above example: Motion Control Module #1 sends its high-speed counter 1 PV and pulse output 1 PV as the synchronous data link bits.

Note	(1)	Synchronous data for Coordinator Modules is fixed to general-purpose
		(ladder execution results) data.
	(2)	If there is no synchronous data to be sent, select no data for Select Syn-
		chronous Data in the System Setup to shorten the synchronous data
		transfer time.
	(3)	Auxiliary Area data is transferred when input and output refresh method
		is set to Immediate refresh and the synchronous data is set to an analog
		input or analog output value in the System Setup.
