    Constant Communication Cycle Time 3.3.1 When a Slave Unit is Withdrawn from Communication Slave units that are no longer available for communication due to power off or other reasons are withdrawn from YHLS communication but communication continues with the remaining normal slave units. Although there is no response for accesses to withdrawn slave units, remote scan time remains constant as no retries are attempted.

  • Page 28: Output Control Function

    Output Control Function This function is used to suspend communications of the YHLS master module with slave units when the sequence CPU module “stops”. To enable this function, set the “Output when Stopped” setting to ‘Reset’ in the DIO setup for the slot installed with the F3LH0-1N master module in the configuration setup of the CPU module.

  • Page 30  Data transfer from sequence CPU module to YHLS master module Data stored in internal devices of the sequence CPU module is transferred to the output area of the YHLS master module by execution of a WRITE instruction. The instruction execution time depends on the sequence CPU type. Moreover, for some sequence CPU types, data transfer time is significantly reduced when the master module is installed in the main unit instead of a sub-unit.
