When input I0 is on, program execution jumps to label 0. LJMP When input I1 is on, program execution jumps to label 1. LJMP LJMP When input I2 is on, program execution jumps to label 2.

  • Page 310 25: U OMMUNICATION NSTRUCTIONS Multi-byte start delimiter  First two bytes can be configured as a multi-byte start delimiter. The incoming data is processed according to the receive format only when the first two bytes of the incoming data match the start delimiter. Therefore, only the incoming data sent to slave station 1 is processed.

  • Page 313 25: U OMMUNICATION NSTRUCTIONS BCC (Block Check Character) The SmartAxis has an automatic BCC calculation function to detect a communication error in incoming data. If a BCC code is designated in the receive format of a RXD instruction, the SmartAxis calculates a BCC value for a specified starting position through the position immediately preceding the BCC and compares the calculation result with the BCC code in the received incoming data.

However, make sure that the folder name specified by the DLOG instruction is not duplicated with the folder names specified by the other DLOG instructions. When the folders are duplicated, log data with a mixed format is output to the same CSV file.
