Frequently Asked Questions
Q: What is the difference between the 3964(R) and ASCII protocol?
A: 3964(R) is a secure, error-checked protocol for reliable data blocks. ASCII is simpler, sending plain text characters, often used with printers or older devices.
Q: Can I connect multiple devices to this single port?
A: No, this is a strict point-to-point module. It is designed for a direct connection to one other device. For multi-drop networks, consider a CP 441 module.
Q: Is the configuration software extra?
A: No, the necessary parameter assignment software is included on the provided CD and integrates into your existing STEP 7 environment.
Q: What type of cable should I use for the full 1200m distance?
A> For maximum distance, use a high-quality, shielded twisted-pair cable (like PROFIBUS cable) and ensure proper termination at both ends of the line.
Q: Does this module support MODBUS communication?
A: Not directly with its built-in drivers. To communicate with a MODBUS device, you would need to use the ASCII protocol and program the MODBUS frame structure in your PLC logic.
