How many parameters could be able to contain a sendmessage command?
FlexSim 17.2.5
Three. As you can read in the Commands Help:
sendmessage
Send a message to an object, firing its OnMessage trigger
Parameters
(obj toobject, obj fromobject [, var par1, var par2, var par3])
Description
Causes a message to be sent immediately to the toobject from the fromobject as in a direct function call. When the toobject receives the message, its OnMessage trigger will fire.
In the code of the OnMessage trigger, you may refer to the fromobject as msgsendingobject, and the three par values passed in as msgparam(1), msgparam(2) and msgparam(3). These message parameters are Variants, meaning they can be numbers, strings, treenode references or arrays.
Example
sendmessage(current.centerObjects[1], current, item, 10);
This sends a message to the object connected to current's first center port. A reference to item is passed as par1 and the number 10 as par2.
Is there a way to send more then 3 parameters? What I am trying to do is send 4 different labels names to a parallel process.
The message parameters are Variants. You can write all of your values into an array and send that as a single parameter. Note though that this is only possible with "sendmessage()". "senddelayedmessage()" can only use numbers as parameters.
sendmessage(toObject, fromObject, [1, 2, 3, 4])
