Introduction
The Integrated Development Environment (IDE) is a dedicated software for the E4J02 series of intelligent delay modules. These modules are equipped with built-in functions such as remote control encoding, real-time clock, and serial port configuration, which can significantly reduce the peripheral components of micro-automation systems, thereby providing a truly integrated solution. The E4J02 series intelligent delay modules read the input states based on the user's input schematic files and control the output states. User drawings can include various common functions such as timing, counting, voltage measurement, and pulse width modulation output, and communication with the host computer can be achieved through the RS-485 interface. This integrated development environment can be used in conjunction with the E4J02 series intelligent delay modules to build micro-automation systems for home, commercial, and industrial use, and it offers good usability and cost-effectiveness while enhancing reliability and reducing integration difficulty. The E4J02 series intelligent delay modules are the best alternatives to glue logic and single-chip microcontroller relay control boards; in some simple functional scenarios, they can even replace low-end Programmable Logic Controllers (PLCs).
For convenience, in the following text, we will refer to the six models B2J0404, B2J0405, E4J0202, E4J0203, E4J0204, and E4J0205 as "low-density modules", and the three models E4J0206, E4J0212, and E4J0218 as "high-density modules".
Introduction to MODBUS-ASCII Protocol
The content of each field in the MODBUS-ASCII protocol is exactly the same as that in the MODBUS-RTU protocol. The only difference is that ASCII requires instructions to be expressed in numeric characters. Additionally, the ASCII protocol requires a colon (:) at the beginning and a carriage return and line feed (\r\n, 0x0D 0x0A) at the end. The checksum used in the ASCII protocol is also different from that in the RTU protocol, being LRC checksum. Compared to the RTU protocol, the ASCII protocol is easier to read, write and program, but has a lower information density and poorer checksum reliability. Generally, it is only used in situations where compatibility with some older industrial control devices is required. This product can intelligently distinguish between ASCII commands and RTU commands, and they will not interfere with each other. Since the support for the ASCII protocol is an additional feature, the maximum character interval still follows the agreement of the RTU protocol [1]. Moreover, the ASCII protocol is not applicable to wireless functions and cannot utilize the host function of this product. The maximum length of the ASCII format supported by this product is 480 bytes; ASCII commands exceeding this length will be directly truncated. For detailed information on the ASCII format and LRC checksum, please refer to relevant materials. Here, we only provide a comparison example of the ASCII format and RTU format; it can be seen that the ASCII format is approximately twice as long as the RTU format.
