➊

The input type can be selected to march the connected sensor. There are two input types specifications:
Thermocouple/Resistance thermometer input and Analog input.

➋

The parameter will not be shown on the Controller display when alarm 3 is not assigned to an output.

➌

Communications parameters are enabled after they have been changed by resetting the controller.

➍

For controllers with two event inputs (events 1 and 2), this cannot be set if the number of Multi-SP uses parameter is set to 1
or 2

➎

For controllers with two event inputs (events 1 and 2), this cannot be set if the number of Multi-SP uses parameter is set to 2.

➏

PRST (program start) can be set even when the program pattern is set to OFF, but the function will be disabled.

➐

The logic of CompoWay/F (900-TC) operation command code 00 (communications writing) is not affected.

➑

The setting (monitor) range depends on the transfer output type setting. (See the setting data list for details.)

➒

P.END (program end output) can be set even when the program pattern is set to OFF, but the
function will be disabled.

➓

The output turns ON when the status of either the Control Output 1 ON/OFF Count Alarm or the Control Output 2 ON/OFF
Count Alarm turns ON.
