Ident Codes for Momentum I/O Bases

General Information about Ident Codes
All Momentum I/O modules have an internal ident code. It is required so that a DP master can identify the types of connected devices. The master compares byte 1 of the ident code of the connected DP devices with the ident codes in the configuration data provided by the service terminal. Application data transmission begins only when the proper device types with the correct device addresses are connected to the bus. In this way, a relatively high security from configuration errors is achieved.
The ident code is visible to you only if it has been entered in the appropriate files (for Momentum modules, file ASA_7512.GSD on diskette 381 SWA 000 00). The user should always use the current GSD file.
From the ident code you can tell which module type has sent a diagnostics message.
