Toyopuc PC3/PC2 Ethernet Driver
Timing
Inter-Request Delay:This property specifies how long the driver waits before sending the next request to
the target device. It overrides the normal polling frequency of tags associated with the device, as well as
one-time reads and writes. This delay can be useful when dealing with devices with slow turnaround times
and in cases where network load is a concern. Configuring a delay for a device affects communications with
all other devices on the channel. It is recommended that users separate any device that requires an inter-
request delay to a separate channel if possible. Other communications properties (such as communication
serialization) can extend this delay. The valid range is 0 to 300,000 milliseconds; however, some drivers may
limit the maximum value due to a function of their particular design. The default is 0, which indicates no
delay between requests with the target device.
Note: Not all drivers support Inter-Request Delay. This setting does not appear if it is not supported by the
driver.
Device Properties - Communications Parameters
Port Number: Specify the port number to 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 Properties - Redundancy
Redundancy is available with the Media-Level Redundancy Plug-in.
