Hi all,
How to program the Real Time Clock in TWIDO PLC. I search the help in which the schedule blocks are used. I have tried my best to use it, but it's not configuring. How it can be configured and how to use the schedule Block. I am using TWDLCA24DRF PLC and The Software is twido soft.
 
I want to start the motor daily From 4PM to 6PM and remain off for the rest of the day. Now I don't know how to do this. I made the changes in the schedule block, but still when I switch on the input of the PLC, it still starts working. How it can be done. Please explain a little bit.
 
This is the program. How can I add to activate the pump according to the real time clock, and where should I use those %SW114.X bits. Please explain.
 
For starters, Real Time clock option does not come inbuilt with TWD..24DRF.

It has to be bought separately (Part no. TWDXCPRTC) and mounted on the PLC.( the port is at the bottom of PLC).

Once you buy/mount the RTC then it is very easy to configure your schedule block.

Click on Schedule block and click the check box "configure"

Select all days and the desired time of output and the desired output address or a flag... and vola...you have it.

Assuming you used %m10 as the output bit then bring % m10 in series with your existing logic.

Cheers.
