General Specification

Instruction for RS485 SEND / RECV

                   Above instruction is used in sequence program of only
                   master PLC being designated as station no. h1F.
Communication Method       Asynchronous half duplex
Max. Linkable station number   32 stations(including self station)
Transmission speed     300 ~ 19200bps(selectable)
Transmission distance         Max. 1km(no repeater)
Preset of waiting time     Preset address = D060
for Time Out Error        Preset value(x 10ms) = 0 ~ 255 (0ms ~ 2550ms)
                   (Default preset value = 0(500ms),
                   if preset value is equal or more than 255, waiting
                   time is 2550ms.)
