When used in a remote I/O setting, the processor has a 64 max I/O words per drop (64 in / 64 out). The max number of remote drops is 31. These can be a mix of discrete or register I/O. For each word of configured I/O, one of the I/O words must be deducted from the total available. When used in a distributed I/O setting, the 140CPU31110 can only have a one network per system, unless it is being used with a 140NOM21x00 option module – then it can have 3 networks per system. The max words per node are 30 in and 32 out in a distributed I/O system. Additionally, 64 is the maximum number of DIO drops per network in this configuration.
