Toyopuc PC3/PC2 Ethernet Driver
Setup
Supported Devices
Toyopuc PC3, PC2 and PC10G series
The PC2 model selection can be used with PC3 > PLCs operating in the PC2 Interchange mode.
Note: This driver is limited to 1024 devices.
Communication Protocol
Toyopuc PC3/PC2 Ethernet Computer Link Protocol
Connection Timeout
This property specifies the time that the driver will wait for a connection to be made with a device.
Depending on network load, the connect time may vary with each connection attempt. The default setting is
5 seconds. The valid range is 1 to 30 seconds.
Note: Making a connection with a device can be very time consuming. When connecting with multiple
devices located at different IP addresses or port numbers, define an additional Toyopuc Ethernet channel in
the OPC Server project for this unique device. Connecting to multiple devices using the Relay Command
through a single IP and port number will not cause a new connection to be opened and will not incur a
connection delay.
Port Number
This property specifies the port number that will be used to connect to the Toyopuc PLC. The Toyopuc EN-I/F
Ethernet PC3/PC2 module supports eight ports for communications. Each port must be dedicated to a single
connection. When specifying a port number, ensure that no other Ethernet node will attempt to use this port
number on the target Toyopuc PLC. The same port number can be used when communicating with multiple
Toyopuc PLCs.
Device IDs
The Device ID, specified as YYY.YYY.YYY.YYY[P1,L1, S1, L2, S2, P3, L3, S3], is used to specify the Device IP
address along with Relay Command Link/Exchange information on the Ethernet network. YYY designates the
Device IP address: each YYY byte should be in the range of 0 to 255.
Note: A request can be relayed through one device to another device configured with the same link
module, such as HPC-Link or FL-net. This relay connection is established by appending a link/exchange path
to the device IP address. The following image illustrates the use of the routing path between HPC-linked
devices:
