#168 - What are the main differences between these two Digital Input Cards

What's the main differences between these two Digital Input Cards:

6ES7131-6BF01-0BA0 vs. 6ES7131-6BH01-0BA0.

> Number of Digital inputs: F = 8, H = 16

> 24V Encoder Power Supply: F = Yes, H = No

> Base Unit selection for connection variants:

F:
1-wire connection BU type A0 2-wire connection BU type A0 3-wire connection BU type A0 with AUX terminals or potential distributor module 4-wire connection BU type A0 + Potential isolation module

H:
1-wire connection BU type A0 2-wire connection BU type A0 + Potential isolation module 3-wire connection BU type A0 + Potential isolation module 4-wire connection BU type A0 + Potential isolation module

> Short-circuit diagnostics: F = Yes, H = No

Note:

Hardware diagnoses, such as wire-break, can be detected by "enabling wire-break diagnostics" in the Hardware configuration, then by adding the OB82 "Diagnostics Error Interrupt" and moving the OB's inputs, "IOstate" (WORD), "laddr" (HW_ANY), "Channel" (UINT) and "multierror" (BOOL) to myDB. The events are then recorded in "Online Diagnostics" and in the "Diagnostics Buffer".
