Our controllers come with a convenient password function as a security measure that prevents others from changing the controller's settings.

Models Supported
All models of UT100 Series (including UP150) and Green Series (excluding UD310, UD320, and UD350)

With these controllers, the input sensor type and control output type are set using parameters, and those setting parameters are combined into a setup parameter group. The password function restricts access to that setup parameter group. In other words, security is maintained because only people who know the password can gain access.
The following is an example with the UT351.

Password Function Example

As this is a matter of security, forgotten passwords can only be recovered by having them sent from the Yokogawa factory.
