Setting Procedure For Tracking Transfer - Mitsubishi Electric MELSEC iQ-R Series User Manual

Tracking trigger
By turning on a tracking trigger, the devices or labels of a range specified in the corresponding tracking block are transferred.
Bits used as tracking triggers change depending on the CPU parameter setting, as shown below.
■When "Tracking Device/Label Setting" is set to "Transfer collectively"
The bit 0 of SD1667 is used as a tracking trigger. The bit is automatically turned on by the system at an initial processing or
operating status change (STOP to RUN), and the tracking transfer is started. To stop the tracking transfer, turn off the bit. To
restart, turn on the bit.
■When "Tracking Device/Label Setting" is set to "Detailed setting"
SD1667 to SD1670 (64 bits) are used as tracking triggers. The bit 0 of SD1667 to the bit 15 of SD1670 correspond to the
tracking blocks No.1 to 64. To start the tracking transfer of a tracking block, turn on the corresponding bit. To stop the tracking,
turn off the bit. To restart the tracking transfer, turn on the bit again.
When "Tracking Block No.1 Auto Transfer Setting" is set to "Transfer Automatically" in the CPU parameter, the bit 0 of
SD1667 is automatically turned on by the system at initial processing or operating status change from STOP to RUN, and the
tracking transfer is started.
Ex.
Program example for changing the status of tracking transfer triggers according to conditions
• When only M0 (Trigger switching condition 1) is on, the tracking transfer trigger of the tracking block No.1 is turned on. (Tracking blocks No.2 to No.64 are not
transferred.)
• When only M1 (Trigger switching condition 2) is on, the tracking transfer trigger of the tracking block No.2 is turned on. (Tracking blocks No.1 and No.3 to
No.64 are not transferred.)

Setting procedure for tracking transfer

The following describes the setting procedure for tracking transfer.
1.
Set "Tracking Setting" in the CPU parameter. ( Page 395 Tracking transfer setting)
2.
Add a program that controls tracking triggers. ( Page 394 Tracking trigger)
3.
Write the set parameters and program to the CPU module with the engineering tool.
4.
Start up the system again.
5.
Turn on the tracking trigger with the program to start the tracking transfer.
When "Tracking Device/Label Setting" is set to "Transfer collectively", the above steps 2 and 5 are not required.
To continue the same control as before even after system switching, configure the settings in "Tracking
Setting" so that all data necessary for the program is transferred.
