Siemens 6DD2920-0AA0 Module

Introduction

Since replacing the PLC CPU also requires changing the PLC entireback plane, any modules that were previously used in the S5 rack must also bereplaced. This includes all I/O modules, function modules, and communicationmodules. c. Interface Modules in Local Expansion Racks In legacy S5applications, there may have been more than one tier of modules (localexpansion racks) connected to the main rack. In these cases, all the moduleswill have to be replaced with S7 modules. If using the S7-300 family, a similararchitecture can be achieved using the IM360, IM361, and IM365 modules toexpand the main rack. If using the S7-400 family, the IM460 and IM461 are used.Another possible thing to consider is to move the modules to a remote rack anduse the IM463 interface as shown below. This might be cost effective since youcould reuse the S5 I/O modules. The following sketch shows remote racks of S5type connected to a S7 main rack through the IM463. Note this could be a possiblesetup for both intermediate performance and high performance systems. The IM463interface is very easy to program. Very similar to a DP coupler in that it hasS5 addresses assigned on one side and S7 addresses assigned on the other side.Experience has proven that the correct length of the 721 cable is important.There is a switch on the front of the IM463 module which must be set to thelength of the 721 cable. There are 4 choices for length. Again, the other wayto migrate the system would be to convert the remote racks and all of themodules to ET200M. It may be wise to make several estimates of hardwareconversions, and choose the most cost effective approach.
