(2) Functions
• For the EN311, this is the function block to request module control, TCP/IP protocol,
and/or UDP/IP protocol communication.
• When an execution request(REQ) becomes TRUE(ON) from FALSE(OFF), the N
number of received data words will be routed from receive data P with the contents of
the specified transmission command (CMD).
• The number of received data words, 1-1001 can be specified (It depends on the
socket service command).
• When the reception completes, the completion output(DONE) becomes TRUE(ON) for
one scanning time and the corresponding socket number is displayed on the STATUS.
