Stack Configuration

This chapter lists all functions that are used to configure the EtherNet/IP stack. These functions must be called within appl_setup() before goal_eipNew() was called. Otherwise these functions have no effect. Each configuration has a default value that will be applied if no other value was set.

res = goal_eipCfgDomainNameSet("example.org");

goal_eipCfgHostNameSet

res = goal_eipCfgHostNameSet("example_device");

goal_eipCfgNumExplicitConSet

Set the maximum number of explicit Connections the device can handle at once.

Default Value: 6

Table: goal_eipCfgNumExplicitConSet parameters

res = goal_eipCfgNumExplicitConSet(10);

goal_eipCfgNumImplicitConSet

Set the maximum number of implicit Connections the device can handle at once.

Default Value: 6

Table: goal_eipCfgNumImplicitConSet parameters

res = goal_eipCfgNumImplicitConSet(10);

goal_eipCfgEthLinkCountersOn

Enable support for Ethernet Link attributes 4, 5, 12 and 13. The hardware must support the appropriate counters.

Default Value: GOAL_TRUE

Table: goal_eipCfgEthLinkCountersOn parameters

res = goal_eipCfgEthLinkCountersOn(GOAL_TRUE);

goal_eipCfgEthLinkControlOn

Enable support for Ethernet Link attribute 6. The hardware must support forced link speeds and duplex modes.

Default Value: GOAL_TRUE

Table: goal_eipCfgEthLinkControlOn parameters

res = goal_eipCfgEthLinkControlOn(GOAL_TRUE);

goal_eipCfgChangeEthAfterResetOn

A change of Ethernet link speeds or duplex modes requires a reset of the device. The hardware must support forced link speeds and duplex modes.

Default Value: GOAL_FALSE

Table: goal_eipCfgChangeEthAfterResetOn parameters

res = goal_eipCfgChangeEthAfterResetOn(GOAL_FALSE);

goal_eipCfgChangeIpAfterResetOn

A change of the IP address requires a reset of the device.

Default Value: GOAL_FALSE

Table: goal_eipCfgChangeIpAfterResetOn parameters

res = goal_eipCfgChangeIpAfterResetOn(GOAL_FALSE);

goal_eipCfgNumSessionsSet

Set the number of Encapsulation sessions the device can handle at once.

Default Value: 20

Table: goal_eipCfgNumSessionsSet parameters

res = goal_eipCfgNumSessionsSet(10);

goal_eipCfgTickSet

goal_eipCfgO2TRunIdleHeaderOn

Default Value: GOAL_TRUE

Enable the Run/Idle Header for consumed (Originator-to-Target) cyclic data.

Table: goal_eipCfgO2TRunIdleHeaderOn parameters

res = goal_eipCfgO2TRunIdleHeaderOn(GOAL_TRUE);

goal_eipCfgT2ORunIdleHeaderOn

Enable the Run/Idle Header for produced (Target-to-Originator) cyclic data.

Default Value: GOAL_FALSE

Table: goal_eipCfgT2ORunIdleHeaderOn parameters

res = goal_eipCfgT2ORunIdleHeaderOn(GOAL_FALSE);

goal_eipCfgQoSOn

Enable support of the QoS object.

Default Value: GOAL_TRUE

Table: goal_eipCfgQoSOn parameters

res = goal_eipCfgQoSOn(GOAL_TRUE);

goal_eipCfgNumDelayedEncapMsgSet

Set the number of Encapsulation messages that can be delayed at the same time.

Default Value: 2

Table: goal_eipCfgNumDelayedEncapMsgSet parameters

res = goal__eipCfgNumDelayedEncapMsgSet(2);

goal_eipCfgDhcpOn

Enable the DHCP client if it is supported by the platform.

Default Value: GOAL_FALSE

Table: goal_eipCfgDhcpOn parameters

res = goal_eipCfgDhcpOn(GOAL_TRUE);

goal_eipCfgDlrOn

Enable support of the DLR object. This feature requires the DLR stack and support of the hardware.

Default Value: GOAL_FALSE

Table: goal_eipCfgDlrOn parameters

res = goal_eipCfgDlrOn(GOAL_TRUE);

goal_eipCfgAcdOn

Enable support for Address Conflict Detection (ACD).

Default Value: GOAL_FALSE

Table: goal_eipCfgAcdOn

res = goal_eipCfgAcdOn(GOAL_TRUE);

goal_eipCfgAcdConflictBehavior

Configure Behavior if Address Conflict Detection (ACD) detects an address conflict. There are three configurations possible, where DHCP is prioritized:

• Transit into error state and do nothing: pass ipAddress = 0 and flgDhcpEnable = GOAL_FALSE,

• Set fallback IP configuration: pass valid IP configuration and flgDhcpEnable = GOAL_FALSE,

• Get IP per DHCP: pass flgDhcpEnable = GOAL_TRUE.

Default Value: flgDhcpEnable = GOAL_TRUE

Table: goal_eipCfgAcdOn

uint32_t ipAddress = GOAL_NET_IPV4(192, 168, 0, 100);
uint32_t subnetMask = GOAL_NET_IPV4(255, 255, 255, 0);
uint32_t gateway = GOAL_NET_IPV4(192, 168, 0, 1);
GOAL_BOOL_T flgDhcpEnable = GOAL_FALSE;

res = goal_eipCfgAcdConflictBehavior(ipAddress, subnetMask, gateway, flgDhcpEnable);
