How Does GPIB-ENET/100 Communication Work from Multiple Systems?Hardware: Instrument Connectivity Other>>Ethernet>>GPIB-ENET/100
Problem: Can I access a GPIB-ENET/100 instrument from multiple computers at the same time? Solution: Yes. Because the GPIB-ENET/100 is a networked device with an IP address, multiple computers can access and control the same GPIB-ENET/100. When this situation occurs the GPIB-ENET/100 takes one command at a time and processes commands in order. For example, if computer #1 does a write, such as ibwrt *IDN?, and then computer #2 did a read, such as ibrd 500, computer #2 would read the response generated from computer #1’s write. Computer #1 would no longer be able to read the response because the buffer would be clear. One computer can take or give up sole access to a GPIB-ENET/100 by using the iblock and ibunlock commands. This operation can be performed on either the board or device level. If one computer does an iblock on the board level, then another computer will receive the error ELCK when performing an ibfind on the board. Scan for Instruments in Measurement & Automation Explorer will also fail if another computer has locked the board or device.Related Links: KnowledgeBase 2YME4VK8.
