The following figure shows the processor board CPU and arrangement of the mod-
ules.
The interface modules are located on the processor printed circuit boards CPU (No.1
in Figure 3-3 to 3-8) of the devices 7SJ62/63/64.
Please note the following:
• Only interface modules of devices for panel and cubicle flush mounting as well as
of mounting devices with detached operator panel or without operator panel are re-
placeable. Interface modules of devices in surface mounting housings with two-tier
terminals must be exchanged in our manufacturing centre.
• 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 ap-
plicable); see margin heading „Termination".
