Allan Bradley Micro Logix 1500

Anybody have any good training resources on this unit, besides the manual? I have limited PLC training, but will be attending a class covering Allan Bradley units. As far as I know, the unit is interfaced with a DAT module which I think allows the user to change the I/O or ladder logic in the unit. Is this right?
Since I will be using this PLC for a while, I'll be a frequent on this forum.

Thanks in advance for any help

Its called a DTAM not DAT, Data Table Access Module, it can be used to access and change data, what can be changed depends on the type of DTAM module.

Ron,
