Notes
EMCY Send Event.
This event is sent by the application to set the error code in the CANopen stack for
the PHD.
The example below assumes the Storyboard application is set up to call Lua function
canopen_set_error with arguments of
code
,
reg
, count and
value
.
Lua Example function canopen_rx_emcy ( mapargs )
local ev = mapargs .context_event_data
local code = ev [" error_code "]
local reg = ev [" error_reg "]
local count = ev [" count "]
local value = ev [" value "]
local data = {}
if ( code ~= nil and reg ~= nil and count ~= nil and value ~= nil )
then
data [" code "] = code
data [" reg "] = reg
data [" count "] = count
data [" value "] = value
gre. send_event_data(" cos.set_error ",
"2 u1 error_code 1u1 error_reg 1u1 count 2u1 value ",
data , " cos ")
end
end
