Installation and Usage Notes

This submodule inserts into the CPU compartment under the front cover. You must align the notch correctly before pushing it in. The Siemens 6ES5340-3KA11 requires an EPROM programmer for initial loading. Therefore, prepare your logic offline before inserting the submodule. Always handle this card by its plastic edges only. Static discharge from your fingers will permanently corrupt the stored program data.
