GE Multilin C60 Breaker Management Relay B-5APPENDIX B 0.1 FUNCTION CODESBB.1.7 FUNCTION CODE 05H: EXECUTE OPERATIONThis function code allows the master to perform various operations in the relay. Available operations are in the table SUM-MARY OF OPERATION CODES.The following table shows the format of the master and slave packets. The example shows a master device requesting theslave device 11H (17 dec) to perform a reset. The hi and lo CODE VALUE bytes always have the values ëFFí and ë00írespectively and are a remnant of the original Modbus Æ definition of this function code.B.1.8 FUNCTION CODE 06H: STORE SINGLE SETTINGThis function code allows the master to modify the contents of a single setting register in an relay. Setting registers arealways 16 bit (two byte) values transmitted high order byte first.The following table shows the format of the master and slave packets. The example shows a master device storing thevalue 200 at memory map address 4051h to slave device 11h (17 dec).Table Bñ4: MASTER AND SLAVE DEVICE PACKET TRANSMISSION EXAMPLEMASTER TRANSMISSION SLAVE RESPONSEPACKET FORMAT EXAMPLE (HEX) PACKET FORMAT EXAMPLE (HEX)SLAVE ADDRESS 11 SLAVE ADDRESS 11FUNCTION CODE 05 FUNCTION CODE 05OPERATION CODE - hi 00 OPERATION CODE - hi 00OPERATION CODE - lo 01 OPERATION CODE - lo 01CODE VALUE - hi FF CODE VALUE - hi FFCODE VALUE - lo 00 CODE VALUE - lo 00CRC - lo DF CRC - lo DFCRC - hi 6A CRC - hi 6ATable Bñ5: SUMMARY OF OPERATION CODES (FUNCTION CODE 05H)OPERATIONCODE (HEX)DEFINITION DESCRIPTION0000 NO OPERATION Does not do anything.0001 RESET Performs the same function as the faceplate RESET key.0005 CLEAR EVENT RECORDS Performs the same function as the faceplate CLEAR EVENT RECORDS menucommand.0006 CLEAR OSCILLOGRAPHY Clears all oscillography records.1000 to 101F VIRTUAL IN 1-32 ON/OFF Sets the states of Virtual Inputs 1 to 32 either ìONî or ìOFFî.Table Bñ6: MASTER AND SLAVE DEVICE PACKET TRANSMISSION EXAMPLEMASTER TRANSMISSION SLAVE RESPONSEPACKET FORMAT EXAMPLE (HEX) PACKET FORMAT EXAMPLE (HEX)SLAVE ADDRESS 11 SLAVE ADDRESS 11FUNCTION CODE 06 FUNCTION CODE 06DATA STARTING ADDRESS - hi 40 DATA STARTING ADDRESS - hi 40DATA STARTING ADDRESS - lo 51 DATA STARTING ADDRESS - lo 51DATA - hi 00 DATA - hi 00DATA - lo C8 DATA - lo C8CRC - lo CE CRC - lo CECRC - hi DD CRC - hi DDwww .
