| Question | Why do I not see all the discrete tags in a pushbutton object? |
| Answer | You may have defined tags as discrete but if the PLC addresses assigned to these tags are read only addresses, then you will not see these tags. The reason is because a pushbutton writes discrete data to the PLC address and if a tag is mapped to a ReadOnly PLC address, the pushbutton is not allowed to write the data. |
