Configuration Notes:
The following figure shows an example of a multimaster network with multiple masters and one slave.

Fig. 1

The following figure shows a multimaster network with multiple masters that communicate with multiple slaves.

Fig. 2

The PC with STEP 7 Micro/WIN and the HMI device are both masters. The S7-200 CPUs are slaves in both cases.

Note:
The following cables are multimaster-compatible:
