Page 8: Section 1 - Introduction
OVERVIEW This document describes the LAN-90 PCV Harmony Protocol Specific Driver (PSD) for data communication with the Bailey-Fischer & Porter MICRO-DCI controllers. This PSD contains all device specific descriptives for address- ing the various MICRO-DCI devices for data communication. The PSD initiates all communication transactions for the inter- face. -

Page 13: Section 3 - Configuration
SECTION 3 - CONFIGURATION PSD START-UP FILE The PSD task is started by the Harmony Executive which assigns a task ID and priority and passes a start-up file name. (See the following example format descriptions.) The start-up file is an ASCII text file in which text lines of the following for- mat contain the start-up arguments: p:XXXXXXXXXX i:X b:BBBB d:N s:N a:XXX p: Specifies a port identification name, XXXXXXXXXX ,... -

CONFIGURATION ® w: NNN w: Specifies delay time NNN when the Executive message exchange mode is Not Reply Blocked. When Reply Blocked is specified, the delay time is ignored. The delay (sleep) time is invoked when the Harmony Executive requires no action from the PSD. -
Page 15: Harmony Data Type 0, Unsigned Integer
CONFIGURATION Harmony Data Type 0, Unsigned Integer A Harmony data type 0 (Unsigned Integer) is associated with MICRO-DCI B-Type variables only. B-Type values have a range 0 to 255. The maximum number of B-Type variables that may be assigned to a Harmony data group is 50. Harmony Data Type 4, Float Harmony data type four (Float) is associated with MICRO-DCI C-Type values. -
Page 16: Section 4 - Operation
SECTION 4 - OPERATION OVERVIEW The PSD software works in tandem with the Harmony 90 sys- tem option to provide an interface between LAN-90 PCV and the MICRO-DCI system. The LAN-90 PCV hardware link up to the RS-485 multidrop network of MICRO-DCI controllers is through an RS-232-C port to an external RS-232-C/RS-485 adapter. -
Page 17: Psd Primary Functions
OPERATION ® PSD PRIMARY FUNCTIONS The primary role of the PSD is to provide protocol specific com- munication for exchanging data between the LAN-90 PCV Har- mony Executive and the MICRO-DCI controllers that are addressable via the specified ports. Only the driver contains external device and communication protocol specific data. -
Page 18: Group Size, Generic Versus Micro-Dci Data Type
OPERATION For example, L800 would indicate to the driver that the group contains digital elements and that the first element of the group is 800 in the controller. A tag could be assigned to any of the elements up to, but not including, the limit of the group size plus the starting address. -
