Also, when using the board in the MELSECNET/10 network system, refer to "For QnA/Q4AR Corresponding MELSECNET/10 network system reference manual".
1 OVERVIEW MELSEC POINT (1) For MELSECNET/H, select QCPUs, RCPUs, and Q compatible network modules. (2) If QnACPU or ACPU are included in the same network, select MELSECNET/10 mode which is compatible with MELSECNET/10. (3) All of network modules and MELSECNET/H boards within the same network must be set to the same mode (network type) 1: MELSECNET/H mode, MELSECNET/H Extended mode and MELSECNET/10 mode are available.
1 OVERVIEW MELSEC (4) Compatible with multiple CPU systems. By using station designations of logical station No. on the MNETH utility, MELSECNET/H board is capable of communicating with a multiple CPU system. (5) Compatible with redundant CPU systems. Only by specifying whether the destination is a control or standby station using the user program, access is simply made without considering the current operating system state of the redundant CPU system.
1 OVERVIEW MELSEC (9) External power supply allows continuous network communication even during power-off of personal computer.

12 APPLICATION FUNCTIONS MELSEC 12.2 Low-Speed Cyclic Transmission Function POINT The Q00J/Q00/Q01CPU does not support the low-speed cyclic transmission function. Therefore, the low-speed cyclic transmission function cannot be used in MELSECNET/H that connects the Q00J/Q00/Q01CPU. The low-speed cyclic transmission function is convenient when sending data that does not require high-speed transfer to other stations in a batch mode using the cyclic devices (LB/LW).
12 APPLICATION FUNCTIONS MELSEC 12.2.1 Send range settings Each station's send range of link devices (low-speed LB, low-speed LW) is assigned to the extended area (2000 to 3FFF) in 16-point units for LB (start : 0 to end F) and in one-point units for LW. Each station's send range can also be assigned using a random station number assignment sequence.
12 APPLICATION FUNCTIONS MELSEC 12.2.2 Send timing The low-speed cyclic transmission is executed separately from the normal cyclic transmission. This section describes the setting, processing interval and link cycle of the low-speed cyclic transmission. (1) Transmission setting The link cycle of the low-speed cyclic transmission varies depending on its transmission setting.

By omitting year, month, and day in the setting, the low-speed cycle transmission can be activated yearly (or monthly, or daily). Hour, minute and second values must be entered.
12 APPLICATION FUNCTIONS MELSEC 12.3 Transient Transmission Function The transient transmission function performs data communication only when it is requested between stations. In the MELSECNET/H, data communication can be performed with other stations having the same network number (the same network as where the host is connected), as well as with stations having other network numbers.
12 APPLICATION FUNCTIONS MELSEC 12.3.1 Communication function (1) Parameter settings Set the execution conditions for the transient transmission with the parameters listed below. In the default settings, both the number of transients that one network can execute in one link scan ("Maximum no. of transients in 1 scan") and the number of transients that one station can execute in one link scan ("Maximum no.
12 APPLICATION FUNCTIONS MELSEC (2) Transient transmission range In a multiple network system of the MELSECNET/H, communication can be performed with stations in a maximum of eight networks by setting the routing parameters described in Section 12.3.2. The following diagram illustrates the transient transmission range using an example where the destinations are limited to eight networks.
12 APPLICATION FUNCTIONS MELSEC [Transient transmission valid range] The following table shows the valid ranges of send/receive by transient transmission using the network configuration on the previous page. In the table below, , and indicate whether or not the transient transmission between the request source (destination) listed in the column at the left and the request destination (source) listed in the row at the bottom is possible.
12 APPLICATION FUNCTIONS MELSEC 12.3.2 Routing function The routing function is used to execute transient transmissions to stations having other network numbers in a multiple network system. In order to execute the routing function, it is necessary to set the "routing parameters" to associate the network numbers of the request source and the station that will function as a bridge between the networks.
12 APPLICATION FUNCTIONS MELSEC Setting for 2N 4 that function as a bridge It is not necessary to set the routing to the Transfer to because the host is on the same network as the destination transfer (3). However, it is necessary to set the Transfer from network number (1) as the Transfer to network number and to designate the relay station (2M 1) and the...

Single network system It is not necessary to set the routing parameters for the transient transmission to the same network.
12 APPLICATION FUNCTIONS MELSEC POINT (1) When a network is connected in a loop as shown in the figure below, make sure to set the routing parameters so that the same relay station is routed for both the "route from request source to request designation" and the "route back from request destination to request source."...
12 APPLICATION FUNCTIONS MELSEC (4) Calculation of transmission delay time The processing time of the transient transmission instruction to access a station on other network in a multiple network system can be obtained by adding the following transmission delay factors.

In addition, there are two types of routing parameter settings; one is used when sending data from the request source to the request destination (when sending a request), and the other is used when returning from the request destination to the request source (when sending a response).
12 APPLICATION FUNCTIONS MELSEC 12.3.3 Group function The group function is used to group the target stations of a transient transmission and send data to all of the stations in a group with a single instruction. One network may have a maximum of 32 groups. By setting a group designation to the target station number in the control data of a dedicated instruction, stations with the matching group number retrieve the transient data.
12 APPLICATION FUNCTIONS MELSEC 12.3.4 SEND/RECV function The SEND/RECV function sends/receives data to/from other station's programmable controller using the MELSEC data link library function. This function supports the SEND/RECV instruction of link dedicated instruction. POINT For details of the functions, refer to "MELSEC Data Link Library Reference Manual".
