8. Modbus Help Vlinx MESR9xx Modbus Gateway 7. Modbus Help Modbus ASCII/RTU Basics The Modbus protocol emerged in the mid-1970s as an early protocol for linking terminals with Modicon PLCs using a master/slave (sometimes called a master/client) relationship. A simple, open, message-based protocol, it caught on quickly and became a de facto standard in the industry.
PAGE 66
8. Modbus Help Vlinx MESR9xx Modbus Gateway Slowing down the polling rate may be helpful if power cycling doesn’t cure the problem. A common misperception is that every serial network must terminate with a resistor. While this was true of early serial network configurations, it’s typically the wrong answer – call our technical support and verify if you’re an exception, at 815.433.5100 option 3. A sometimes difficult problem is difference in grounding voltage between various network locations.
