Chapter 16 PLC Function ApplicationsMH300
After leaving the PLC register window, the register setting screen will appear, as
shown below:
If there is a new PLC program and no settings have been made yet, you can read default data
from the converter, and merely edit it to suit the current application.
If settings have already been made, however, the special D in the CANopen area will display the
saved status (the CANopen D area is located at D1090 to D1099 and D2000 to D2399). Assuming
it is a new program, we will first read the default data from the converter; check the
communications format if there is no communications link (the default PLC station number is 2,
9600, 7N2, ASCII). Perform the following steps:
1. Switch the PLC to Stop status
2. Press the transmit button
3. Click on read memory after exiting the window
4. Ignore D0–D399
5. Click on the confirm button.
