The control systems listed above have new functions and technical properties which are described in this

supplement.

1. Section 1 of the supplement lists the technical properties and data for the special I/Os with which the

C7-623/A and C7-626/A control systems are equipped.

2. Section 18 of the supplement is an extract from the manual System Software for S7-300/400 - System and

Standard Functions (hence the unusual number) and contains a description of the new communication

functions for non-configured connections.

3. The execution times are listed in Appendix B of this supplement (an extract from the manual S7-300

Programmable Controller, Hardware and Installation). The execution times for the CPU 314 apply to the

C7-623/624, and the execution times for the CPU 315/-2 DP apply to the C7-626/626 DP.

This supplement contains additional information about the products. If uncertainties arise, this information

should be considered more up-to-date than the information in the manuals and catalogs.

1.1 Properties of the I/Os of the C7-623/A

and C7-626/A Control Systems

Overview

Chapters 1 to 4 of this addendum describe the differences between the two

control systems C7-623/A and C7-626/A and the control systems C7-623 and

C7-626. With the exception of the properties of the I/Os, the properties of the

control systems described in the manuals of the C7-623 and C7-626 are as

described in the manuals.

The following table contains an overview of the I/Os of the control systems.

Pinout of the

Digital Inputs and

Digital Outputs

The pinout of the digital inputs and digital outputs is identical to the pinout of

the C7-623 and C7-626 control systems. The digital universal inputs have been

removed. The pins that were used on the C7-623 and C7-626 for the digital

universal inputs are now used for additional analog outputs.
