Below Modules can connect The S7-1200 to a PROFIBUS fieldbus system
communications modules:
a. CM 1242-5 6GK7242-5DX30-0XE0 Operates as DP slave
b.CM 1243-5 6GK7243-5DX30-0XE0 Operates as DP master class 1
If a CM 1242-5 and a CM 1243-5 both are installed, S7-1200 can perform the following tasks simultaneously:
a. Slave of a higher-level DP master system
and
b. Master of a lower-level DP master system
