Modbus RTU to Modbus ASCII, but is a different question, or do the same. The difference is clear conclusion.
Different encryption methods by Modbus ASCII is ASCII code format, but that it is the Modbus RTU Bi Na Ry memory size is less data to be sent simultaneously to many Modbus RTU,
So surely that will be sent information. faster when large amounts of data.
The same principle is used for sending data is the same.

Table1. Modbus data structure

Both Modbus ASCII and Modbus RTU Address, but can identify different ASCII is a direct Hex base with two bytes when using Modbus RTU one byte. (more…)

I think,many plc user of omron should be has question for what is the different between CPM2A and C200HX-CPU44 of omron controller.

There are 2 different Ethernet adapter for PLC Series CP.
1 is designed CP1W-CIF41 Omron Japan, the other is the U.S. Omron developed CP1W-ETN01-USA.
They have slightly different data, but are very similar in concept.
One of the two devices is essentially an Ethernet serial converter, so that both some limitations on an Ethernet module on the bus directly to the PLC CPU as CS and CJ Ethernet modules are compared.

The CP1W-CIF41 uses the protocol Toolbus on the PLC, and has a maximum length frame of ~ 1000 bytes.
The CP1W-ETN01 US-CV-mode uses the Host Link protocol on the PLC, and has a maximum length frame of ~ 500 bytes. (more…)

Someone has found problem in the CPU 250-1 of KOYO PLC on K- Sequence communication mode which can not run on DirectNet mode Sure! as We need to change protocol from old to new protocol which is K- Sequence,How to if you need to change the protocol to DirectNET. Could you follow thus as step and picture below.

Step 1.Click open program file.

Go to Setup Sec. Comm Port to Change the protocol.

Click menu bar : PLC–>Setup–>Setup Sec. Comm Port…. (more…)
