The C-more HMI (human machine interface) is one of the best values in industrial HMI. Not only do you get competitive pricing but the ease of setup and use will save you even more.
In this video, we show how to log messages used in the message database or the lookup text object. This data logging can be useful in the collection of messages to user or capturing process data for later inspection.
This video is part of the C-more HMI setup videos that give direction on how to set up, use and maintain your industrial HMI.

In C-more HMI you can log messages that are displayed using the Lookup Text Object or the Multi-State Text Indicator. These messages are then time-stamped and stored in a CSV file that is saved on a SD card or USB drive. By default, this CSV file stores on SD card 1 but you can change this setting by going into the panel manager here and then changing this setting. This log file completes each day at midnight and then increments to the next day with the date at the end of the file name. With the Lookup Text Object, the message list used for this object comes from the message database here. Any message that is displayed using the Lookup Text Object and has this function selected will have that message logged to the message database log file. This message can comprise of static text and have the time and date stamped to it and can have multiple discrete, numeric or string tags embedded into the message. When using a numeric or string tag in the message, the value of those tags will be embedded into the message. The discretes will trigger a different static text message, based upon the ON or OFF state of the discrete. Once the message is created, notice that there is a message number here. To trigger this message, the numeric tag used in this Lookup Text Object must match this number for the message to display and then ultimately log if you have the logging function selected. One thing to point out here - if you are using multiple Lookup Text Objects, they will all be using the same group of messages from the message database. This is the main difference when using the Multi-State Text Indicator. The Multi-State Text Indicator functions basically the same as the Lookup Text Object, but with each Multi-State Text Indicator it has it’s own list of messages, specific to that object. If we look at the Multi-State Text Indicator message option, you can create up to 255 messages per object. Each message can also comprise of static text have the time and date stamped to it and can use multiple discretes, numeric or string tags to embed the message to it. The messages that get logged are the ones that have this option selected and are displayed using this object. So, to wrap up you can log complex messages that have static text or tags embedded into the message and have them logged to the message database log file. The messages that get logged are the ones that are triggered using the Lookup Text Object that use the global message database or you can log messages from multiple Multi-State Text Indicators that have their own local message list. This gives you plenty of options and solutions to get your job done and the data logged. Just another way that C-more is proven to be the best value in HMIs.
