I want to read and write memory blocks with loader commands by using Ethernet to connect between SX. Is there any limitation to the amounts of data...

The amounts of data transmitted or received are not limited as R_WRITE instruction/R_READ instruction but by the capacity of the memory from/to which data ar... Show Detail

I have lost the 'IP address' set with the WEB module (Type_ NP1L-WE1). How can I restore the factory setting?

It is not possible for the user to restore the factory setting. The module will have to be returned to the factory for initialization for a fee. Contact ou... Show Detail

When I use the Ethernet module (NP1L-ET1), can I use a same message port No. (SPORT_NO) to establish multiple connections (use multiple M_OPEN)?

The SX does not allow the use of a single SPORT_NO (range_ 1 to 127) for multiple connections simultaneously. When you want to connect multiple ports, use a ... Show Detail

When I forget the IP address of the WEB module (Type_ NP1L-WE1), can I change the IP from an external network?

No, you can't. You can check the IP address by connecting the PC loader to the CPU module and monitoring the RAS information of the fault diagnosis function. Show Detail

When I use an Ethernet module (Type_ NP1L-ET□) to download the system definitions and module driver, a file transfer error is generated. Why?

The file transfer error occurs because the module driver is downloaded with the Ethernet module not recognized by the CPU. For the CPU to recognize the Ethe... Show Detail

I use the Ethernet module (NP1L-ET1/ET2) and using communication FB (M_OPEN). M_OPEN sets two ports of RPORT_NO and SPORT_NO. Does this mean that o...

One M_OPEN consumes one port of SPORT_NO, which is the local port. RPORT_NO is the port of the other end of the communication seen from the SX. Show Detail

After I replaced an Ethernet module (Type_NP1L-ET1/ET2), it cannot communicate with the target device. What is a possible cause?

The IP address and port standard No. of the self station of the Ethernet module are stored in the internal ROM of the Ethernet module. After replacing an Eth... Show Detail

During loader command communication of Ethernet, a port is closed after it has not been accessed from a personal computer for a certain period of t...

In the parameter setting of the Ethernet module in the system definition, set the 'Server FTP command watch timer value' to 0. The port is not closed even if... Show Detail

I use the Ethernet module (Type_NP1L-ET1). Is the IP address assigned automatically?

The IP address is not assigned automatically. (DHCP function is not supported.) The default IP address is '192.168.0.1'. You can check the IP address b... Show Detail

I understand that when data are received via an Ethernet network in the TCP/IP unpassive mode, requests from multiple nodes can be accepted. How ca...

Input an arbitrary address. This setting is ignored for the unpassive mode. Show Detail
