First of all, check to see that your system meets the mininum requirements to use Dual Channel modules. FieldPoint Explorer must be version 2.0.2 or later (which you meet), and depending upon your network module, you must have firmware revision 201 or greater (FP-1600) or 28 or greater (FP-1000 and FP-1001).
Next we have to look at behavior of the system. In FieldPoint Explorer, empty slots in FP-TB-10's default to Discrete Inputs. This can mean one of two things for your system. First of all, it might mean that you have not re-detected your modules (right click on the comm resource in FieldPoint Explorer,choose Edit This Comm Resource and then choose Find Devices or start a new IAK file, create a new comm resource and choose Find Devices). If it still does not s
how up, it means that the module is not being recognized by the terminal base. Remove and re-insert the module as you may not have locked it in place the first time. When a module is inserted for the first time in a slot, the power and ready LED's on the FP-TB-10 should turn off and on.
If removing and re-inserting does not fix it, you can also try reseting the network module by right clicking on the network module and choosing Edit This Device. There is a check-box that says "Factory Configuration", check it and press the Reset button. You will then need to uncheck and re-do any configurations you have done for the modules attached to that network module, and should be able to do a Find Devices and have it detect it.
