Mitsubishi Electric MELSEC iQ-R Series - Sending an SLMP Frame

1638
18 CC-LINK IE FIELD NETWORK INSTRUCTIONS
18.9 Sending an SLMP Frame
18.9 Sending an SLMP Frame
J(P).SLMPREQ, G(P).SLMPREQ
These instructions send an SLMP frame to the SLMP-compatible device in the same network. Data of the target station can
be read/written and operated.
■Execution condition
Setting data
■Description, range, data type
*1 When specifying setting data by using a label, define an array to secure enough operation area and specify an element of the array
label.
• The RnENCPU (network part), RJ71GF11-T2, and RJ71EN71 with firmware version "18" or later support these instructions. (Use an engineering tool with
version "1.035M" or later.)
