Connecting safety components
Connect safety components according to the following safety level by dual wiring and single wiring.
Double wiring
Single wiring
Use the doubling input signal to the CC-Link IE Field Network remote I/O module (with safety functions) with
the following combinations of input terminals. For combinations other than the following, an error is detected
by doubling input discrepancy detection.
{X0, X1}, {X2, X3}, {X4, X5}, {X6, X7}, {X8, X9}, {XA, XB}, {XC, XD}, {XE, XF}, {X10, X11}, {X12, X13}, {X14,
X15}, {X16, X17}, {X18, X19}, {X1A, X1B}, {X1C, X1D}, {X1E, X1F}
To execute the input dark test, connect the safety components using a test pulse terminal.
To execute the input dark test function, use the input terminals and test pulse terminals of the CC-Link IE Field
Network remote I/O module (with safety functions) with the following combinations. Connecting to the
incorrect test pulse terminal is identified as a disconnection and causes an error.
[Correct combination]
{X0, X2, X4, X6, X8, XA, XC, XE} and T0
{X1, X3, X5, X7, X9, XB, XD, XF} and T1
{X10, X12, X14, X16, X18, X1A, X1C, X1E} and T2
{X11, X13, X15, X17, X19, X1B, X1D, X1F} and T3
When not performing input dark test, the COM+ terminal can be used.
Use the dual wiring for the CC-Link IE Field Network remote I/O module (with safety functions) with the
following combinations of output terminals.
{Y0, Y1}, {Y2, Y3}, {Y4, Y5}, {Y6, Y7}
