Establishing Connection To The I/Os - Siemens SIMATIC S5 Manual

IP 265
3 Installation Guidelines
3.1 Assembly and Removal of the IP 265
The IP 265 is to be snapped onto a bus unit in the same way as an I/O module of the S5-100
system. Please note the following for assembly and removal of the module:
• The IP 265 may only be connected or disconnected without load voltage and in the STOP mode
of the CPU.
• The memory submodule may only be inserted or removed in the POWER OFF state of the CPU.
• The IP 265 may only be plugged into slots 0 to 7.
• The maximum permissible number of IP 265 modules is limited depending on the S5 system:
- In the S5-100, S5-95 and ET 200, a maximum of six IP 265 modules can be connected.
- In the S5-90, you can connect up to two IP 265 modules
Setting the coding element
Like every I/O module, the IP 265 is provided with a white coding key on the back. The coding key
of the IP 265 is always set to number 6. The bus unit has a white, rotating counterpart for every slot:
the coding element. If you want to snap the module onto the bus unit, you must also turn the coding
element to "6" so that the coding key can snap into place in the coding element.
3.2

Establishing Connection to the I/Os

The following electrical connections are to be established according to your particular application:
• Connection of 24 V digital inputs of the module to sensors in the plant
• Connection of 24 V digital outputs of the module to actuators in the plant
• Connection of differential inputs of the module to encoders with error signals
• Connection of expansion inputs/outputs of two IP 265 modules.
Sections 3.2.1 to 3.2.4 show you how to establish the connections.
Note
The shields of the signal cables are to be connected to the connector casing and the
shield/protective ground conductor rail.
Cable interface conditions
For the correct operation of the IP 265, important principles must be considered when laying and
shielding the connecting cables. Since the IP 265 can only be used in connection with the S5-100,
S5-90/95 or ET 200, we assume that you have one of the relevant manuals available. These
manuals contain detailed explanations of all cable interface conditions for programmable controllers
(PLCs).
