C-More EA9 HMI to Solo and Click PLC Controllers




The cmore EA9 HMI has an event manager that can be used to trigger actions based on various events.
C-More EA9 HMI Solo and Click PLC controllers
We will be adding a Click PLC to our headless RHMI cmore EA9 program that we created last time to communicate to the solo process temperature controller. The Solo will be connected via RS485 using the Modbus RTU protocol. Using the Modbus TCP protocol we will connect the Click PLC to the Ethernet port. Using the event manager we will be writing the set value (SV) and present value (PV) of the solo process temperature controller to the Click PLC. We will also allow the Click PLC to write the SV into the solo. This is in addition to the writing of the set value via remote apps and the solo itself. Let’s get started.

Headless RHMI to Solo Process Temperature ControllerVideo

Watch the video below to see the headless cmore unit work with the Solo and Click PLC controllers. The cmore will write the set value (SV) and present value (PV) of the Solo process temperature controller to the Click PLC. Through the event manager, we will read a set value (SV) from the Click PLC and place it into the Solo. The Click PLC SV will then be set to zero. (0)

Event Manager – C-More EA9 

The Event Manager allows the C-more to take action based on events like changing tag values, day-of-week, time-of-day, or even based on a particular screen change. The actions can include setting a tag value, copying tag data between tags, changing the screen, capturing a screen, playing a sound file, even sending an e-mail (including embedded tag data, screen captures, or PLC log files). Previously, we used the event manager to add alarms.

We will select the Display Large Key Pad On Panel. This option makes the editing of the parameters easier for larger fingers. Ease of use is also better for remote access.
Select OK.

Event Manager Database – C-More EA9 HMI

C-More EA9 HMI Solo and Click PLC controllers
Select from the main menu | Database | Event Manager Database… Alternatively, you can select the Event Manager Database under the Database heading in the Function tab of the Navigation window.

Select the Add icon in the Event Manager window.

Enter the Event name as Solo Values to Click.

We are going to create an event to copy the Solo PV and Solo SV values into the Click Memory area once be second. We will use the one-second clock bit flag in the Click PLC for the timing.
Select the three dots next to the Tag Name field in the Tag-a section.

We will be using the following memory areas for our DEV002 (Click PLC) in our Cmore headless unit.
PV_SOLO_CLICK – Unsigned int 16 – DS3 – Read/Write
SV_SOLO_CLICK – Unsigned int 16 – DS4 – Read/Write
SOLO SV CLICK – Unsigned int 16 – DS20 – Read/Write – Set SV from Click
SOLO SV CLICK 0000 – Unsigned int 16 – DS21 – Read/Write – Reset SV value in Click
SC7 ONE SEC PULSE – Discrete ON/OFF – SC7 – Read/Write
Select the one-second pulse (SC7) and select OK.

Select Tag Copy. This will copy the contents of one tag into another.

The source tag will be the PV_Solo. This is the present value of the solo temperature controller. The destination tag will be PV_SOLO_CLICK this will be the memory tag DS
3 of the Click PLC.

Select the delete action button. We will not require an alarm each time the information is copied to the Click PLC. (1-second interval)
C-More EA9 HMI Solo and Click PLC controllers
We have now created our first event for the EA9-RHMI headless cmore. Select the Add button.
C-More EA9 HMI Solo and Click PLC controllers
This will now add our event to the event database.

The next event to add will check to see if the Click PLC has a value to put into the set value (SV) of the Solo. If it does then the value will be copied to the SV of the Solo. Then the value in the Click PLC will then be reset. (Set to 0.)
Select the Add icon in the Event Manager.
C-More EA9 HMI Solo and Click PLC controllers
We will name this event Solo SV from Click. Our tag will be SOLO_SV_CLICK which is the DS20 memory in the click PLC. Under limits select the greater than symbol and the value of 0. Select the Add Action… button.

Click PLC Program – C-More EA9 HMI

We will use the program that we developed in the following post.
Click PLC Logging Data with Time and Date StampVideo
C-More EA9 HMI Solo and Click PLC controllers
In this Click PLC example program, we took a series of consecutive memory locations (DS1 to DS10) and stored them in memory areas DS100 to DS4100 each minute.
We used DS3 as the Solo PV and DS4 as the Solo SV in the click PLC. Last time we used these memory areas as spare locations.
C-More EA9 HMI Solo and Click PLC controllers
DS20 and DS21 have been added to our Data View (Log Parameters View) that we created last time.

  1. The method of connecting Click PLC to the Ethernet port using the Modbus TCP protocol is highly effective. I got to know your blog better later. Thank you sir.
