11: D ATA L INK C OMMUNICATION11-6 FC5A MICROS MART USER’ S MANUAL FC9Y-B1268Data Link Communication between Master and Slave StationsThe master station has 6 data registers assigned to transmit data to a slave station and 6 data registers assigned toreceive data from a slave station. The quantity of data registers for data link can be selected from 0 through 6 usingWindLDR. The following examples illustrate how data is exchanged between the master and slave stations when 2 or 6data registers are used for data link communication with each of 31 slave stations.Example 1: Transmit Data 2 Words and Receive Data 2 WordsMaster StationD8069 Communication ErrorD900 - D901 Transmit DataD906 - D907 Receive DataD8070 Communication ErrorD912 - D913 Transmit DataD918 - D919 Receive DataD8071 Communication ErrorD924 - D925 Transmit DataD930 - D931 Receive DataD8072 Communication ErrorD936 - D937 Transmit DataD942 - D943 Receive DataD8098 Communication ErrorD1248 - D1249 Transmit DataD1254 - D1255 Receive DataD8099 Communication ErrorD1260 - D1261 Transmit DataD1266 - D1267 Receive DataSlave StationsD8069 Communication ErrorSlave Station 1D900 - D901 Transmit DataD906 - D907 Receive DataD8069 Communication ErrorSlave Station 2D900 - D901 Transmit DataD906 - D907 Receive DataD8069 Communication ErrorSlave Station 3D900 - D901 Transmit DataD906 - D907 Receive DataD8069 Communication ErrorSlave Station 4D900 - D901 Transmit DataD906 - D907 Receive DataD8069 Communication ErrorSlave Station 30D900 - D901 Transmit DataD906 - D907 Receive DataD8069 Communication ErrorSlave Station 31D900 - D901 Transmit DataD906 - D907 Receive DataExample 2: Transmit Data 6 Words and Receive Data 6 WordsMaster StationD8069 Communication ErrorD900 - D905 Transmit DataD906 - D911 Receive DataD8070 Communication ErrorD912 - D917 Transmit DataD918 - D923 Receive DataD8071 Communication ErrorD924 - D929 Transmit DataD930 - D935 Receive DataD8072 Communication ErrorD936 - D941 Transmit DataD942 - D947 Receive DataD8098 Communication ErrorD1248 - D1253 Transmit DataD1254 - D1259 Receive DataD8099 Communication ErrorD1260 - D1265 Transmit DataD1266 - D1271 Receive DataSlave StationsD8069 Communication ErrorSlave Station 1D900 - D905 Transmit DataD906 - D911 Receive DataD8069 Communication ErrorSlave Station 2D900 - D905 Transmit DataD906 - D911 Receive DataD8069 Communication ErrorSlave Station 3D900 - D905 Transmit DataD906 - D911 Receive DataD8069 Communication ErrorSlave Station 4D900 - D905 Transmit DataD906 - D911 Receive DataD8069 Communication ErrorSlave Station 30D900 - D905 Transmit DataD906 - D911 Receive DataD8069 Communication ErrorSlave Station 31D900 - D905 Transmit DataD906 - D911 Receive DataNote: When data link is used on port 3 through port 7, data link communication error codes are stored in the consecutive data regis-ters starting from the data register designated in Function Area Settings.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
