Introduction

You can use component communications to connect two or more E5@C slaves to the E5@C-T master
via RS-485 and then transfer the fixed SP or program SP or change the RUN/RESET status for all of
the Controllers at the same time. If you transfer the fixed SP or program SP or change the RUN/RESET
status of the master (i.e., the Controller with a communications unit number of 0), the set points or
RUN/RESET status of all of the slaves (i.e., the Controllers with communications unit numbers other
than 0) that are connected via RS-485 will change automatically. When you transfer the set points, the
set point from the master can be multiplied by a factor or offset at each slave.
• Transferring the Program SP (Program SP Mode)
Master changed to
RUN status.

Programmable Controller
• Transferring the Fixed SP (Fixed SP Mode)
Fixed SP of master
changed to 100.
Note1 To use component communications, the input type and, if an analog input is used, the decimal point
position must be set to the same values for all of the E5@C-T/E5@C Controllers. The operation will not
work correctly if the position of the decimal point is different.
2 When the Reset Operation parameter is set to fixed SP operation, the SP mode status will automatically
change according to the RUN/RESET status. In RUN status, the Controller will change to program SP
mode. In RESET status, the Controller will change to fixed SP mode.
3 The E5@CT that acts as the master automatically changes the write mode of the slave E5@C from backup
mode (mode for writing set values to non-volatile memory) to RAM write mode (supported from July 2016,
items manufactured at our factory (Version 1.2)).
