Conditions for the above table:

a.For the T2N configuration, this table assumes the configuration of figure A.4, in which T2N (PU235N/245N) is mounted in the main base unit.

b.Refer to the T2N User's Manual - Hardware for the processing times for the instructions.

c.This table assumes that for PU245N, 128 words is specified for S20LP PC link protocol transmission (SEND instruction on local port or RECV instruction from remote ports). However, if S20LP PC link protocol transmission is not used, use the PU235N row in the above table, even if there are PU245N unit installed.

d.If less than 128 words are used with the S20LP PC link protocol transmission, the number of words that can be specified during socket transmission on the Ethernet Port can be increased over the values listed in table A.7. If the number of words for S20LP PC link protocol transmission on the PU245N decreased on one word, the number of words for Socket transmission on the Ethernet Port can increase in one word. However, the maximum number of words that can be specified during PC link transmission on the Ethernet Port is 1000 words.
