Context structure , referenced by all ecx functions

Fields

port: *mut ecx_portt

port reference, may include red_port

slavelist: *mut ec_slavet

slavelist reference

slavecount: *mut c_int

number of slaves found in configuration

maxslave: c_int

maximum number of slaves allowed in slavelist

grouplist: *mut ec_groupt

grouplist reference

maxgroup: c_int

maximum number of groups allowed in grouplist

esibuf: *mut uint8

internal, reference to eeprom cache buffer

esimap: *mut uint32

internal, reference to eeprom cache map

esislave: uint16

internal, current slave for eeprom cache

elist: *mut ec_eringt

internal, reference to error list

idxstack: *mut ec_idxstackT

internal, reference to processdata stack buffer info

ecaterror: *mut boolean

reference to ecaterror state

DCtime: *mut int64

reference to last DC time from slaves

SMcommtype: *mut ec_SMcommtypet

internal, SM buffer

PDOassign: *mut ec_PDOassignt

internal, PDO assign list

PDOdesc: *mut ec_PDOdesct

internal, PDO description list

eepSM: *mut ec_eepromSMt

internal, SM list from eeprom

eepFMMU: *mut ec_eepromFMMUt

internal, FMMU list from eeprom

FOEhook: Option<unsafe extern "C" fn(slave: uint16, packetnumber: c_int, datasize: c_int) -> c_int>

registered FoE hook

EOEhook: Option<unsafe extern "C" fn(context: *mut ecx_contextt, slave: uint16, eoembx: *mut c_void) -> c_int>

registered EoE hook

manualstatechange: c_int

flag to control legacy automatic state change or manual state change

userdata: *mut c_void

userdata, promotes application configuration esp. in EC_VER2 with multiple ec_context instances. Note: userdata memory is managed by application, not SOEM
