Chapter 5. Functions
• If relay output or voltage pulse output is set as the control output by the model
No. and if one of functions 1 to 4 is set for the operation type of control outputs
1–2 (ot1.1 to ot2.1), the output assignment A–D setting of control outputs 1–2
(ot1.2 to ot2.5) is displayed and can be changed.
• If a model with event relay outputs is used and if one of functions 1 to 4 is set for
the operation type of event outputs 1–3 (ev1.1 to ev3.1), the output assignment
A–D setting of event outputs 1–3 (ev1.2 to ev3.5) is displayed and can be changed.
Output assignment polarity
Whether to reverse the data assigned to the four inputs (A, B, C, D) used for output
bit functions can be specified.
Item (bank) Display Description Initial value User level

“1st digit” (2nd, etc.) means the first digit
(etc.) from the right.
1st digit: Polarity of output assignment A
2nd digit: Polarity of output assignment B
3rd digit: Polarity of output assignment C
4th digit: Polarity of output assignment D

• If relay output or voltage pulse output is set as the control output by the model
No. and if one of functions 1 to 4 is set for the operation type of control outputs
1–2 (ot1.1 to ot2.1), the polarity A–D setting of control outputs 1–2 (ot1.6 to
ot2.6) is displayed and can be changed.
• If a model with event relay outputs is used and if one of functions 1 to 4 is set for
the operation type of event outputs 1–3 (ev1.1 to ev3.1), the polarity A–D setting
of event outputs 1–3 (ev1.6 to ev3.6) is displayed and can be changed.
Handling Precautions
• Depending on the conditions, the output relay may turn on and off
quickly and repeatedly. To prevent this, observe the following:
•
If 49 (control output 1 terminal status) is set for any of control output 1
output assignments A to D (Ot1.2 to Ot1.5), do not set 1 (reverse) as the
output assignment polarity for the same letter.
•
If 48 (event output 1 terminal status) is set for any of event output 1
output assignments A to D (EV1.2 to EV1.5), do not set 1 (reverse) as the
output assignment polarity for the same letter.
