PCD4 Series controllers

PCD4 programmable controller

Although now obsolete some spares and replacement processors are still available either directly from MACOL or from another source that we may be able to help you locate.

For customers wishing to update to a modern controller we are able to reverse engineer undocumented software and re-write it for the replacement system. This is often the most cost-effective solution offering like-for-like functionality with minimum downtime.

The manual for the PCD4 series is available for download as a ZIP file here.

Up to 510/2048 inputs/outputs: Modular structure with up to 32 sockets for digital, analogue, counting, measuring and/or motion control modules up to 510 central inputs/outputs

up to 2048 local inputs/outputs (e. g. PROFIBUS DP)

Up to 1 MByte user memory: For programs, text and data blocks. 1 MByte flash memory as option for ease of down/uploading program modifications and backups.

Up to 6 serial data ports: Can be fitted with a choice of RS 232, RS 422, RS 485 or TTY/current loop 20 mA.

Field bus connections: Can be fitted with a choice of PROFIBUS FMS, PROFIBUS DP as master or slave and Ethernet-TCP/IP.

Standard inputs: Fast counters and interrupt inputs directly on CPU of controller (only PCD4.M170).

High performance operating system and efficient programming tools

Efficient programming with PG5 due to its many programming languages, such as IL, FUPLA, GRAFTEC etc. and its diagnostic and other add-on tools. An efficient instruction set, comprehensive FBox libraries and a structure that complies with IEC 1131-3 simplify the editing of transparent programs.

Portability of user programs due to harmonized system resources and the integral SAIA®S-Bus, user programs are transferable across the entire PCD family (PCD1 up to PCD6) and capable of running.

Short reaction times due to direct accessing of I/O signals, without the passing through a process map (image).

Flexible network integration due to through communications and programming via Ethernet-TCP/IP to the connected field bus stations PROFIBUS DP or FMS.
