Modbus RTU Advanced Properties

Fields in the Advanced dialog box are as follows:

Advanced Settings	Default	Click to update all fields with their default settings.
	Custom	Click to define custom values for fields on this tab.
Timeout (sec)		Number of seconds the device communication will wait for a response to a poll request before declaring a read failure.

	Domain Type	Write Function
Register Write Function	Coil	5
		15
	Holding	6

Word Reverse		This affects four byte values only (REAL, DINT, UDINT). Some devices store the LOW WORD and HIGH WORD in reverse order (from a Modicon PLC). This will reverse them so they are displayed correctly in CIMPLICITY.
Cache Disable		By default, CIMPLICITY caches continuous addresses into a cache group. It then performs a single read on the group. Some devices will not allow this kind of group read. When caching is disabled, each point is read individually from the device. Note that in projects with large point counts, this can significantly affect performance.
OK		Saves the values in the file \\site_root:data\master_ port .ini, which is then read by the device communication interface the next time it is started.
Cancel		Closes the device dialog box without any modification.
