1-91.3 Restrictions on Unit Combinations1.3.1 Restrictions on FP0 Expansion UnitUp to three expansion units can be added on the right of the FPΣ, these expansion units being eitherexpansion units or intelligent units from the earlier FP0 series, or a combination of the two.A combination of relay output types and transistor output types is also possible.Controllable I/O pointsType os control unit Number of I/O points whenusing control unitNumber of I/O points whenusing FP0 expansion unitFPG-C32 32 ponts Max. 128 pointsFPG-C28 28 points Max. 124 pointsFPG-C24 24 points Max. 120 points Note1)Note1) This is the number of points when combining with the transistor type FP0 expansion unit.Note:• Install the FP0 thermocouple unit on the right side of all other expansion units. If it is installed on theleft side, the total precision will deteriorate.• Install the FP0 CC-Link slave unit on the right side of the other expansion units. There is no expansionconnector on the right side.
