 Flex Network / SIO System Design (Type C)
Connecting Flex Network I/O units to the LT allows the LT to control any remote I/O
unit. When connecting the I/O unit, two channels are available — CH1 and CH2. Each
channel outputs the same data and can be used for data communication.
When using a single channel, the maximum number of I/O units that can be
connected is 31, and when using a second channel, the number increases by 32,
for a total of 63 I/O units.
The LT unit's serial interface allows you to connect to external devices such as
temperature controllers or inverters.
For detailed information about the Flex Network, refer to the Flex
Network User Manual.
For information about external devices, refer to the LT Editor De-
vice Connection Manual (included with the LT Editor software), GP-
PRO/PBIII Device/PLC Connection Manual (included with the C-
Package software) .
