Manage a building looking at an elevator mod. If Schindler provides access to SMLCD on its controller with access to proprietary diagnostic features (but not whatever devices, tools, codes, materials, etc), is that enough to not be tied down with them in the long term so an indepedent can come in and service without issue?

And if they do provide that access, is there any real benefit in going with MCE from the supportability aspect?

Would you consider MCE over TX-R5?
