ATTACHing and DETACHing the Pendant Before an application program can communicate with the pendant, the pendant must first be ATTACHed using the ATTACH instruction. The logical unit number (lun) for the pendant is 1. The following code readies the pendant for communication: t20_lun = 1 ATTACH (t20_lun) As with all other devices that are ATTACHed by a program, the pendant should be DETACHed when the program is finished with the pendant. The following instruction frees up the pendant: DETACH (t20_lun) When the pendant has been ATTACHed by an application program, the user can interact with the pendant without selecting manual mode.
As with all I/O devices, the IOSTAT function should be used to check for errors after each I/O operation. eV+Language User's Guide, v2.x, 18318-000 Rev A Page 179 Command Action to transparent or opaque.
