OPC/DDE server Frequently Asked Questions
| Question | Is it possible to enable and disable a link in DS Data using Visual Basic? |
| Answer | Yes. This is described in Chapter 5 of the DS Data manual. The procedure starts on page 5-8 entitled "Using Subroutines To Read and Write Data." In this procedure instead of setting the LinkItem equal to a memory location in the PLC, set it to "Enable." This Item is one of the many that DS Data predefines for every link created. By writing a "1" to Enable the link is accessible, by writing a "0" it is disabled. |
