Siemens Modbus Tcp License [hot] -

You can craft a Read Holding Registers packet (Function Code 0x03) and send it via TSEND. This requires no Modbus TCP license. However, you must handle timeouts, retries, and error checking manually.

The license is required on the engineering PC , not the PLC. You only need one license per engineer who programs the PLC. Once the code is downloaded to the PLC, the PLC runs the logic indefinitely, even if the engineer disconnects their PC. Disclaimer: Prices and order numbers are subject to change

In the landscape of industrial automation, few communication protocols are as ubiquitous as Modbus. Born in the late 1970s, it remains the de facto standard for connecting countless industrial devices, from sensors and drives to third-party PLCs. Conversely, Siemens SIMATIC controllers, particularly the S7-1200 and S7-1500 series, dominate the high-end automation market with their processing power and integration capabilities.

If you have a large fleet of S7-1500s, buy one floating license per engineer. Do not buy a license per PLC.

That depends on the CPU, not the license. An S7-1500 standard CPU supports up to 64 simultaneous Modbus TCP connections. The license does not limit connection count.
