Cautions
• Do not use extension cable longer than an overall extension length of 13.2m
(43.31ft.).
• When using an extension cable, do not bind it together with the main circuit
(high voltage and heavy current) line or do not lay down them closely to each
other.
• Set up the number of extension stages so that the number is not duplicated
with another.
• When the Q5 B, Q6 B, QA1S6 B, QA6 B, and QA6ADP+A5 B/
A6 B
*1
are used together as the extension base unit, mount the Q5 B/
Q6 B, QA1S6 B, QA6 B, and QA6ADP+A5 B/A6 B in order from the
nearest position of the main base unit. Set the extension stage No. in order,
starting from the Q5 B/Q6 B,
Although there are no particular restrictions on the order of the installation of
the Q5 B and Q6 B, refer to Section 6.1.4 for the availability.
• The Q6 RB cannot be connected as an extension base unit.
• Connect the extension cable from OUT of the extension cable connector of
the base unit to IN of the extension base unit on the next stage.
• If the number of installed modules has exceeded the maximum number of
mountable I/O modules, an error "SP.UNIT LAY ERR." (error code: 2124)
occurs.
* 1: When using the QA1S6 B as the extension base unit, the QA6ADP+A5 B/A6 B cannot be
connected.
