Cir No. (Circuit Number)
Input each Module's circuit number. When two or more of the same model Module are used,
assign circuit numbers in order (1, 2, 3, ...).
The circuit number for Motion Modules (SVA-01, SVA-02, PO-01, and SVB-01) are han-
dled as Motion Module numbers.
The following table shows the range of circuit numbers that can be input for each Module.
Each 217IF Module uses three circuits, so allow three circuit numbers for each Module by
inputting values 3n+1 (1, 4, 7, ...).
Modules other than the 217IF Module use just 1 circuit per Module, so allow just one circuit
number for each Module by inputting consecutive values (1, 2, 3, ...).
Circuit numbers for Motion Modules (SVA-01, SVA-02, PO-01, and SVB-01) are treated as
Motion Module numbers. The maximum number of Motion Modules that can be used in one
system is limited to 16.
The same circuit number cannot be set for more than one of the same type of Module, in sys-
tems using multiple racks (4 max.).
An error will occur when the settings are saved if the same circuit number is set for more
than one Modules.
Module (Dual) (Dual Modules)
Some Modules can be set as Dual Modules to improve reliability.
The following table shows the Modules for which can be set as Dual Modules.
