The B40 Brick variant determines whether HTTPS is available. The standard B40 for EtherNet/IP does not support HTTPS. The B40 for EtherNet/IP IIoT Secure, identified as AB6990, does support HTTPS and requires certificate provisioning.
HTTPS Support by B40 Variant
| Variant | HTTPS support | Certificate requirement |
|---|---|---|
| B40 for EtherNet/IP | No | Not applicable for HTTPS |
| B40 for EtherNet/IP IIoT Secure (AB6990) | Yes | Install a CA certificate and a device certificate |
Certificate Requirements for AB6990
Provision both certificate types on the AB6990: a certificate-authority (CA) certificate and a device certificate. Installing only one does not satisfy the stated HTTPS configuration requirement. The available evidence does not specify certificate formats, key requirements, validity rules, or the installation interface, so obtain those details from the AB6990 download documentation before generating or importing certificates.
Select and Configure the HTTPS-Capable Brick
- Confirm the installed product variant. If it is the standard B40 for EtherNet/IP, HTTPS is unavailable; changing certificates or network settings will not add support.
- Select the B40 for EtherNet/IP IIoT Secure (AB6990) when HTTPS is required.
- Generate or obtain the required CA and device certificates. The Anybus Certificate Generator is identified as one available provisioning method.
- Install both certificates using the procedure documented for AB6990.
Verification and Troubleshooting Boundary
Verify the model identifier before troubleshooting certificates. For AB6990, confirm that both the CA certificate and device certificate were installed. If HTTPS remains unavailable after those checks, consult the AB6990 download documentation because the evidence does not define ports, browser behavior, certificate error messages, firmware dependencies, or additional security settings.
