1. Overview
1.2 System configuration
The T-PSV supports one Ethernet connection and one Serial connection at the same time.
On the Ethernet connection, up to 64 PLCs can be connected.
On the other hand, the Serial connection has three types of connection systems, RS485
computer link connection, programmer port connection, and TOSLINE-S20 connection. Either
one connection system can be selected among these three types.
(1) Ethernet connection
The Ethernet connection is available with T2N, T3H, S2T, S2 and S3. These PLCs can
have an Ethernet interface.
Up to 64 PLCs can be connected to the T-PSV. The transmission speed is 10Mbps. In this
configuration, personal computer's Ethernet port is used.
T-PSV
(2) RS485 Computer link connection
The RS485 computer link connection is available with T1S, T2E, T2N, T3, T3H, S2T, S2
and S3. These PLCs have an RS485 computer link port on the CPU module.
Up to 32 PLCs can be connected to the T-PSV. The transmission speed is up to 19.2kbps.
In this configuration, personal computer's Serial port is used. The RS232C/RS485 converter
(ADP-6237B) is used to convert to RS485.
T-PSV
Note) T1S means T1-16S and T1-40S which has the RS485 communication port.
