Frequently asked questions
Will this rack drop into a panel specified around 6ED1052-1CA00-0BA1?
No — the 6ED1052-1CA00-0BA1 is a LOGO! expansion module, a completely different form factor and bus system. The S7-400 CR2 rack uses a proprietary backplane and is not mechanically or electrically compatible.
