node_acnet_ping_c

	status.i4.v = node_acnet_ping_c(node.i4.v [,millisecs.u4.r])

	This routine will perform an ACNET ping on an ACNET node.

	node		ACNET node (constants are in 'nodedefs')
	[millisecs]	returned millisecond delay in the reply

	This function returns ACNET status values as follows:

	OK			success
	ACNET_NOCON		not connected to ACNET
	ACNET_UTIME		ping failed

	This function requires the following include files:

	cnsparam_h, cbslib_h, nodedefs_h, acnet_errors_h
