For DOP-W series HMI it is possible to customize the layout and input keys for the onboard keypad entry.

These are the default keypad options in DOPSoft:

These options include all the basic keys that are needed in most applications but sometimes the users needs to customize the character entry for their design.

Example 1 : Customer would like to use the HMI for product rating system and log their details such as email address. For this the “@” character is needed which is not available on the custom keypad.

MODBUS TCP communication between C2000 and AH500 in speed mode

Modbus RTU is a famous layer 2 fieldbus protocol used in wide range of applications since the mid 80’s and it has its encapsulation in a Ethernet frame, on TCP/IP protocol of layer 4 – 3 of OSI model. It can be used on Ethernet networks though a logic IP address, Modbus TCP uses the same function codes of RTU. The main advantage is that it is faster and can be used to send or receive data through any Ethernet device such as switches and routers in different topologies like star, tree or other line topologies using TCP/UDP/IP protocols in Layer 3-4. It can be installed in Standard 10, 100 or 1000 Mbit/s Ethernet technology based on copper cables, fiber optics or wireless standards can be used. Number of stations is almost infinite and it can go up to a speed of 1.5 Kbyte per telegram frame.
