FANUC Robotics America GFK-1541B ユーザーズマニュアル

This section describes the programming structures common to all Communications Requests: the
COMMREQ Function Block and the Command Block.

The Communications Request is triggered when the logic program passes power to the
COMMREQ Function Block.

Each of the inputs and outputs are discussed in detail below.  It is important to understand that the
Command Block address points to the location in memory you have setup as the Command
Block.

Enable: 

 Control logic for activating the COMMREQ Function Block. See Section 5 for tips on

developing your program.

  The location of the Command Block.  It can be any valid address within a word-oriented area

of memory (%R, %AI, or %AQ for the Series 90-30 Ethernet Interface).

  A hexadecimal word value that gives the rack (high byte) and slot (low byte) location of

the Ethernet Interface. Note that if using GE Fanuc’s VersaPro PLC software, the leading zeros in
this hexadecimal word value are not displayed on-screen; for example, 0004 will appear as 4.
