HP MicroLogix 1761-NET-ENI manual Node 251 E-Mail Server, Node 252 Bootp Configuration

ENI Configuration (Node 248 to 254) 4-15

Node 251 - E-Mail Server

The TCP/IP address stored in this location defines the mail server. The ENI sends all e-mail requests to this server, which then sends the e-mail message to the destination.

Node 252 - BOOTP Configuration

The ENI allows the BOOTP request to be disabled by clearing the

BOOTP Enable parameter in the channel Configuration File. BOOTP

Enable behaves as follows:

•0 = BOOTP configuration

•1 = soft configuration

When BOOTP Enable is disabled, the ENI will wait for a manual configuration.

The BOOTP enable/disable setting is only evaluated on power-up. Changes to the BOOTP configuration will not take effect until the next power cycle.

IMPORTANT

If BOOTP is disabled, or no BOOTP server exists on the network, you must use a soft configuration method to enter or change the IP address for each ENI. See page 4-1for more information.

See Appendix B for information on using BOOTP.

Node 253 - Baud Rate

The first time the ENI is powered-up (out-of-the-box), it is set to Autobaud so that it can synchronize to the attached controller. The baud rate can be changed by sending a message to address 253 with one of the configuration values shown in the table below. Changes to the baud rate take effect when the ENI power is cycled or when a Save configuration to flash command (write to node 248) is received. The configuration value is sent as a 2-byte integer (1 element from an integer file).

The ENI also performs a CRC/BCC check when autobaud is operational. It reads a test PCCC_Diagnostic Status Request to determine if CRC or BCC is being used and adjusts to it.
