(Note 1) The above figure shows the case that S1=U100 (built-in ET-LAN in the CPU unit) and S2=U1
(connection number 1) are specified by the UNITSEL instruction. Set a desired value for [S2].

Outline of operation
● This instruction sends an EIP message when the execution condition turns ON.
● This instruction specifies the Ethernet unit to be targeted by the UNITSEL instruction.
● A UCMM message set by the EIPMSATT and EIPMBODY instructions is sent.
● The response is stored.
● Call this instruction after X6B (EIP preparation done) turns ON. If it is called before X6B turns
ON, the EIP communication preparation incomplete error is returned.
● The instruction cannot be used in interrupt programs.
● Multiple EIPMSEND instructions cannot be executed simultaneously. A multiple execution
error occurs. The next execution must be executed after confirming the completion of an
instruction.
