| Frequently Asked Questions | |
|
Q1: What is the function of the 10100/2/1 Horizontal Bus Driver module? (via connector CN1) and drives a flat-cable horizontal bus (via front flat cable and connector CN3) that routes to I/O modules across the rack. It also terminates the address-selection line of I/O modules via the horizontal bus. Q2: What power/voltage does it require? With flat cable A1 or A21: 5 V DC, 35 mA. With flat cable A22: 5 V DC, 65 mA. Q3: Can this module be installed/replaced while the system is powered (hot-swap)? central part will be shut down when replaced.” So yes, but with caution — especially if used in a safety-critical part of the system. Q4: What flat-cable versions are used and what's the difference? A1 cable: for non-redundant I/O. A21 cable: for redundant I/O. |
