2.2.3 High-speed I/O communication specifications
Item Specifications
Communication style
Peer-to-peer communication (between the S10mini and
MELSEC)
Applicable Mitsubishi sequencer Sequencer or motion controller in which the MELSEC
A Series Ethernet interface unit (Model AJ71E71 or
equivalent) is mounted
Port number used Fixed at 34100 (decimal notation; for both the S10mini
and MELSEC)
IP address used Any address is usable. However, the S10mini and
MELSEC must agree with each other in network
address.
Supported communication function Cyclic communication based on the MELSEC's fixed-
buffer communication function (asynchronous)
S10mini communication areas Bit registers: X, Y, J, Q, R, M, G, and E registers
Word registers: DW and FW registers
Up to four areas can be specified for transmission and
reception each.
Transmission/reception
communication word count Bit register: 40 words max.
Word register: 256 words max.
(256 words maximum for a total of four areas)
Communication cycle Determined according to the transmission/reception
word count, communication delay time, and MELSEC
response time. See Section 4.11, "Communication
Cycle."
I/O data consistency guarantee unit One word
Note: For the fixed-buffer communication function (asynchronous) of MELSEC, refer to the
MELSEC documentation.
