PORT0 adopts the RS232, and the Mini DIN8 socket. 1 RS-485, USB interface is Type-C. The
right extension module interface is used for extension module connection, the left extension
module is used for communication module connection. RUN and STOP switched by MODE
selection. Two RS-485 terminal resistor, the resistance is 120Ω.

Filtering
function
Digital filter
X0~X7 have digital filtering function. Filtering time: 0~60ms setting by user
programing.
Hardware
filter
Input terminals other than X0 ~ X7 are of hardware filtering. Filtering time: about
10ms
High speed function
X0~X7: high-speed counting, interrupt, and pulse catching
X0 and X1: up to 50kHz counting frequency
X2~X5: up to 10kHz counting frequency
The sum of input frequency should be less than 60kHz
Common terminal
Only one common terminal: S/S
The counter input port has a corresponding maximum frequency limit.. Any frequency higher
than that may result in incorrect counting or abnormal system operation. Make sure that the
input terminal arrangement is reasonable and external sensors used are proper.
PLC provides a port "S/S" to select the input mode of the signal, which can be set to source
input mode or sink input mode. Connect "S/S" to "
＋
24V", that is, set to sink input mode, and
NPN type sensor can be connected.
Input connection example
The following diagram shows an example of VC1-1614MAR in connection with an VC-
0808ENR, which realizes simple positioning control. The positioning signals from the PG are
input through high speed counting terminals X0 and X1, the limit switch signals that require
