Introduction
1. System Design
2. Flex Network Unit Types
This chapter explains the standard system design for the Flex Network unit, and
the types of units available.
The following information explains how to connect the GLC to a Flex Network
I/F and I/O Unit.
When connecting the I/O unit, 2 channels are available - CH1 and CH2. Each
channel outputs the same data and either can be used for data transmission.
The maximum number of connectable units, when using a single channel, is 31,
and when using a second channel, the number increases by 32 to a total of 63.
• The Flex Network uses high speed data transfer technology, and if a
is cable used for data transfer that is not the same as that specified
in this document, network data transfer performance cannot be guar-
anteed. Thus, be sure to use only the cable(s) recommended here.
3.2.1 Connecting the Flex Network Data Transfer Cable
• When connecting the Flex Network I/F unit to a GLC 300 Series op-
erator interface, the optional Bus Conversion unit is required. (Model
No. GLC300-BCB41).
• When turning the entire system's power ON, turn on the I/O unit's
power supply before turning on the GLC's power.
