Note : 1. Communication port 2 is HMI resource, which needs to be set
in MEGVIEW2 for use. Modbus slave station is the default.
Communication port 4, 5 and 6 are HMI resources, which need to be
set in MEGVIEW2 for use
6. Switching characteristics of input and output
6.1 Switching input characteristics and signal
specifications
The counter input port has a maximum frequency limit. If the limit is
exceeded, the count may be inaccurate or the system may not function
properly. Please arrange the input port reasonably and select the
appropriate external sensor.
The PLC provides port "S/S" for selecting whether the input signal is
source input or leak input.
