2 REPLACEMENT OF CPU MODULE
2 - 7
*1 The CPU module with the communications function can be replaced with the CPU module and the communication module
as listed in the following table.
*2 The instruction for file registers and special function modules need to be replaced with those for the Q series.
*3 The High-speed Universal model QCPU (QnUDVCPU) supports an SD memory card.
*4 For a bus connection with the Q00UJCPU, the number of extension stages must be 2 stages or less (including GOT).
For a bus connection with the Q00UCPU, Q01UCPU and Q02UCPU, the number of extension stages must be 4 stages or
less (including GOT).
