What is the function of this communication module?
The Mitsubishi A1SJ71QC24N is a serial communication module designed for MELSEC QnAS Series programmable controllers. It facilitates RS232C communication, allowing these controllers to interface with other devices and networks, enhancing their capabilities in industrial automation systems.
What are the voltage and current specifications of this module?
This module operates at 5 V DC and has an internal current consumption of 0.35 A.
What is the maximum data transfer rate supported by this module?
The module supports a maximum data transfer rate of 115200 bits per second.
Can I use the same program with an alternative model if I replace this module?
When replacing the A1SJ71QC24N with an alternative model, it is generally possible to use the same program. However, due to differences in internal processing speeds and other specifications, it's crucial to confirm the operation and adjust communication timings if necessary.
What should I consider regarding the internal current consumption when replacing this module?
When replacing this module, ensure that the internal current consumption of the new module does not exceed the capacity of your existing power supply. The A1SJ71QC24N has a slightly higher current consumption compared to some older models, which should be taken into account.
Are there any specific adjustments needed when setting up communication protocols with this module?
Yes, adjustments may be necessary, especially regarding communication timing. For dedicated protocols, you might need to specify 'Message wait' times to align with the scanning times of the CPU in the new setup. For nonprocedural or bidirectional protocols, adjusting the data transmission timing might be required.
