General features

All interfaces have the following common features:

• Compact configuration:
  The rugged plastics housing contains the interfaces for the connecting cables.
• Simple mounting:
  The interface modules are mounted on the DIN rail (slot 3) and connected to the I/O modules via a bus connector just like any other module.
• Problem-free configuration:
  The interface modules are self-configuring. Address assignment is not required.
• Status and fault LEDs

IM 365

The IM 365 is the low-cost expansion for an ER. It contains the following features:

• One of the two IM 365 modules is inserted in the CC, the other into the ER. The modules are connected by a fixed cable 1 m in length.
• Limited use of modules:
  The ER is not connected to the C bus (communication bus). Therefore, no C bus nodes (e.g., CPs and FMs, see configuring aids) may be inserted into the ER.
• No separate power supply:
  The modules in the ER are powered by the CPU power supply.

IM 360/IM 361

IM 360 and IM 361 are the ideal solution for comprehensive expansions. They contain the following features:

• IM 360 plugs into CC
• IM 361 plugs into each ER
• Separate power supply
  Each IM 361 requires an external 24 V DC power supply. This then powers all modules of the respective ER. A PS 307 load power supply can be connected using a power connector.
• No module selection restrictions:
  All S7-300 modules can be used in the ER.
