About network parameters when building MELSECNET/10 with Q02HCPU-A

Q02(H)CPU-A is the AnUCPU equivalent. When establishing a MELSECNET/10 network, set the refresh parameter with which SB/SW data is transferred to "Y/D" or o... More Details >>

How to relay CC-Link cables

Use a T-branch repeater module instead of a terminal block. More Details >>

Using a FROM/TO instruction after AJ71UC24 is replaced with QJ71C24N

I/O signals and buffer memory addresses need to be changed but data communications can be conducted using a FROM/TO instruction and X/Y signals. More Details >>

Intelligent Buffer Select of the CC-Link parameter

Set the size of buffer memory used for transient transmission (by dedicated instructions) to local stations, the standby master station, and intelligent devi... More Details >>

Whether or not multiple QJ72LP25-25 modules can be mounted

No, only a single QJ72LP25-25 can be mounted (and is to be mounted on the CPU slot on a main base unit). More Details >>

Relation between CC-Link terminals and signal lines

The following shows the relations between CC-Link terminals and signal lines. - DA : Blue -DB: White -DG: Yellow More Details >>

Clearing data in the QJ71C24N's receiving area buffer memory

Receiving data overwrites the buffer memory data. Writing 0 with a program can be performed but is unnecessary as the data is overwritten. More Details >>

Difference between AJ65SBTB1-16DT1 and AJ65SBTB1-16DT2

Major differences are shown below. - AJ65SBTB1-16DT1 - Rated input current approx. 5 mA - ON voltage/ON current 15 VDC or higher/3.0 mA or higher - O... More Details >>

Necessity of terminating resistors in CC-Link communication

No, it is unnecessary. Terminating resistors are only required at both ends of the network. More Details >>

Overall cable distance and station-to-station distance in CC-Link networks

The overall cable distance and station-to-station distance depend on the version and the transmission speed. Figure 1 shows the case with Ver.1.10-compatibl... More Details >>
