CHAPTER 3: USING THE SNAP ETHERNET I/O DRIVER TOOLKIT Return Value Name Code (Hex) SIOMM_BRAIN_ERROR_RESERVED E007 Reserved SIOMM_BRAIN_ERROR_BUSY E008 The brain is busy. SIOMM_BRAIN_ERROR_CANT_ERASE_FLASH E009 Flash memory cannot be erased. SIOMM_BRAIN_ERROR_CANT_PROG_FLASH E00A Flash memory cannot be programmed. SIOMM_BRAIN_ERROR_IMAGE_TOO_SMALL E00B Downloaded image is too small. SIOMM_BRAIN_ERROR_IMAGE_CRC_MISMATCH E00C Image CRC mismatch SIOMM_BRAIN_ERROR_IMAGE_LEN_MISMATCH E00D Image length mismatch SIOMM_BRAIN_ERROR_FEATURE_NOT_IMPL E00E Feature not implemented SIOMM_BRAIN_ERROR_WATCHDOG_TIMEOUT E00F Communications watchdog timeout OptoSnapIoMemMap Interface Connection Methods Use the following methods to connect to a brain. Method Description OpenEnet V [in] string strIpAddressArg [in] long nPort [in] long nOpenTimeOutMS [in] long nAutoPUC OpenEnet2 [in] string strIpAddressArg [in] long nPort [in] long nOpenTimeOutMS [in] long nAutoPUC [in] long nConnectionType 62 SNAP Ethernet-Based I/O Units Protocols and Programming Guide Indicates Starts the connection process to a brain via TCP/IP. Use the IsOpenDone() method to check whether the open process is completed. bstrIpAddressArg is a string representing the IP address of the Ethernet-based brain, such as 10.192.54.1. The format of the string is not verified. nPort is the IP port used to connect to the brain. The default is 2001. nOpenTimeOutMS is the timeout period in milliseconds for the open process. A different timeout is used for normal communications. See SetCommOptions below. If nAutoPUC is a non-zero value, the Powerup Clear flag on the brain is automatically set. If zero, you must send a Powerup Clear by using the SetStatusOperation(1) method. (See the Status Write Methods table on page 71.) Same as OpenEnet() above, except it allows TCP or UDP to be specified. nConnectionType is 1 for TCP and 2 for UDP.
IsOpenDone V Close V Return Values Return values are shown on page 61. Point Configuration Methods CHAPTER 3: USING THE SNAP ETHERNET I/O DRIVER TOOLKIT Method Description SetCommOptions V [in] long nTimeOutMS [in] long nReserved Use after a call to OpenEnet() or OpenEnet2() to check whether the connection process is completed. Will return SIOMM_ERROR_NOT_CONNECTED_YET (-7) until the connection is completed, a timeout occurs, or another error occurs. Using this function in a program provides a way for the user to cancel the connection process. See the Visual Basic examples for more information. Closes the connection to the brain. Sets options for communication with the brain. nTimeOutMS is the timeout value in milliseconds for communications to the SNAP brain. nReserved is not currently used and should be set to zero. v The OptoSnapIoMemMapX ActiveX component has a variant-only version of this method. Use the following methods to configure I/O points. For more information, see “Referencing SNAP I/O Points” on page 13 and “Configuring I/O Points” on page 18.

Configures a digital point with the specified point type and feature. For digital feature values, see page 125. Configures an analog point with the specified point type, offset, gain, and scale. See “Configuring I/O Points” on page 18. Configures a point with the specified point type, feature, offset, gain, scale, and watchdog. See “Configuring I/O Points” on page 18. For digital feature values, see page 125. SNAP Ethernet-Based I/O Units Protocols and Programming Guide 63
