Are there any restrictions on which slots input/output modules for SMARTDAC+ GX/GP series are installed into?

If using the product's reference junction compensation function with GX90XA module thermocouple inputs, do not install a "GX90XA-10-C1" mA module or "GX90WD" digital input module into the slot to the right^* of the GX90XA module (the side with the smaller slot number). If you install those modules there, RJC accuracy cannot be guaranteed.
*When looking from the back panel of the GX/GP main unit or the front panel of an expansion unit.
