Exchanging Interface Modules
The following figure shows the processor board CPU and arrangement of the modules.
Figure 3-19 Processor board CPU with interface modules
The interface modules are located on the processor printed circuit boards CPU (No.1 in Figure 3-3 to 3-6) of
the devices 7SJ62/64.
Please note the following:
• The interface modules can only be exchanged in devices designed for panel and cubicle mounting and
surface-mounted devices with detached or without operator panel. Devices in surface-mounted housings
with two-tier terminals have to be retrofitted at our factory.
• Use only interface modules that can be ordered in our facilities (see also Appendix A).
• For interfaces with bus capability, ensure that the bus termination is correct (if applicable); see margin
heading „Termination“.
