When I write parameter to LonWorks module (NP1L-LW1) using support tool for a LonWorks (NP4N-LNDF), what is the required cable?

You don't need a dedicated cable. Since the parameters will be set via the CPU module, you need a loader cable for the PLC and the program loader software. Show Detail

When using a communication module (NP1L-RS1/RS2/RS3/RS4/RS), the FB outputs R_STS 'C0' (Hardware error detected) during receiving. In this case, ho...

The received data is cleared to 0. Therefore, be sure not to read (ignore) the data by application program. Reopening the FB (turning the 'OPEN' terminal fro... Show Detail

In the communication module (NP1L-RS1/RS2/RS3/RS4/RS5), is it possible to change communication parameter such as fixed length to variable length af...

Yes, it is possible. Of the parameter setting items of initialization, changes made to specific parameter items (such as frame detection, code conversion and... Show Detail

I want to access the data memory in the MICREX-SX CPU from a PC via the RS-232C port of the general-purpose communication module. (Data read/write)

You can access the memory from a PC by setting the general-purpose communication module (Type_ NP1L-RS2) to 'Loader' mode. Various loader commands have been... Show Detail

There is an OPC server that supports the MICREX-SX (communication middleware, Type_ NP4N-MDLW). Is there an OPC client?

A 'client' is a device that collects data. Since the PLC is a device from which data is collected, there is no OPC client. Show Detail

The total extension of the SX bus has exceeded 25 m. Is there anything to relay the connection?

The bus can be extended with the SX bus electrical repeater (Type_ NP2L-RP1). Up to three repeaters can be used in one system. (When three repeaters are us... Show Detail

Does an RS-485 communication module (Type_ NP1L-RS1/RS4/RS5, etc.) support the MODBUS procedure?

The SX-Programmer Expert supports MODBUS communication (master function) using an FB. Communication with a MODBUS slave device is possible by using SPH_CP... Show Detail

With the FL-net module (NP1L-FL1/FL2/FL3), is there any way to confirm that the data sent from the node-A have actually been received by the node-B?

When the common memory system is used, this can be achieved by handshaking with an application using part of the link memory. Without handshaking, it is not... Show Detail

When the communication cable is disconnected with an FL-net module (Type_ NP1L-FL1/FL2/FL3), are the FL-net common memory data retained? Or are the...

They are retained. Note, however, that they are cleared if the power of the FL-net module is turned off. Show Detail

What will the operation be when the general-purpose communication parameter 8 of the non-procedure standard expansion FB for communication _Cfr* is...

It enables reception only when CD (Carrier Detection) is ON. (Other operations are the same as those in the DTE mode.) Show Detail
