„Block Communication Function for LED Display

To display LED data for ASCII display that is synchronized to each digit, set data for each digit and validate this set data by display selection by communication (Communication Number FA65). Synchronization can also be achieved by batch writing LED data parameters after changing the fol- lowing block communication mode parameters and by sending data by block communication.

Writing in the block communication function will be writing in the RAM only due to the EEPROM life for write operations. The LED data will reset to the initial value ““ when the power is turned off, in failure resetting or when standard shipment settings are set.

„Parameter Setting

“Block communication mode (Communication Number FA80)”

Setting range: 0, 1 (Initial value 0)

0:Block communication parameters ( - ) is used

1:LED display ASCII data is used (When writing, ASCII display data 1 [Communication Num- ber FA70 - FA74], when reading, LED data displayed before change)

*To validate LED data set by using LED display block communication, set standard monitor display selection to “communication LED select ( = ) and display selection by communication to “ASCII data 1 (Communication Number FA65).

„Format

The format is the same as that used in the usual block communication mode. (For the detail infor- mation, see “4.1.3 Block communication transmission format”) The block communication pa- rameters ( - ) will become invalid. Write data will become ASCII display data 1 (Communication Number :FA70 - FA74) fixed. LED display data that is actually being output will be read during reading. The specification range for write operations is 0 to 5.

„Example

Communication LED selection ( = ) for standard monitor display selection. ASCII data 1 (Communication Number:FA65 = 1) for display selection by communication.

LED display ASCII data (Communication Number: FA80 = 1) for the block communication mode. Current LED display status is display of initial value “”
